I am a student. Usually I used to sit more than 8 hours a day in chair. Now a days I am feeling very much pain on regions of backbone and neck. Is this a chance of disk failure?
The most powerful and amazing organ in our body is the brain. It differs from many other organs of our body not only by its shape, but also by its special type of cell called neurons. When these cells gets affected or dead it can never be reverted or regenerated which is the most exclusive nature found only in brain cells. The cells in other parts of our body has the capacity to regenerate (can be replaced or new one can be grown or produced), but brain cells are exception. Hence any damage to the brain, injury or trauma is really a crucial thing to be considered with utmost care.
Brain surgeries really need skill, proper training, confidence and intelligence to perform this highly complicated and risky surgery.
Brain surgeries are performed to:
- Remove the brain tissues that are grown abnormally
- Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
- Biopsy purpose or to remove the tumour
- Make a nerve free
- Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
- To implant artificial electronic device as a treatment for conditions like Parkinson’s disease
- Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
- Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
- Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
- Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.
- Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
- Risk related to the brain surgeries are seizures, coma, swelling of brain, infection to brain or meanings, surgical wound infection that intrudes to the brain structures, abnormal clot formation and bleeding.
- General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain. If you wish to discuss about any specific problem, you can consult a neurosurgeon.
Noncancerous growths of the muscle tissue surrounding the uterus are known as uterine fibroids. This is a common disease which about 70 to 80% of women contract by the time they are 50 years of age. The uterine fibroids can sometimes be very big and cause heavy periods as well as severe abdominal pain while at other times, uterine fibroids give no signs or symptoms whatsoever and go away on their own. This is why it is crucial to know what type of uterine fibroids you have and how to diagnose them. Here are the types of uterine fibroids and how to diagnose them;
There are three main types of uterine fibroids. They are;
- Intramural fibroids: The most common type of uterine fibroids are intramural fibroids. They typically appear in the endometrium and may grow larger which results in your womb getting stretched.
- Subserosal fibroids: Subserosal fibroids are called so because they form on the serosa. The serosa is the outside of your uterus. Sometimes, Subserosal fibroids may grow so large that your uterus appears bigger on one side.
- Pedunculated fibroids: Pedunculated fibroids tumors are basically Subserosal fibroids with a stem. A base which supports the tumor is called the stem.
There are a number of tests done to diagnose uterine fibroids. They are;
- Pelvic exam: A pelvic exam is a thorough inspection of a woman’s pelvic area. The organs which are in the pelvic area include the cervix, ovaries, uterus and vagina. Normally, this and the next test in this article are enough to diagnose uterine fibroids.
- Medical history: The history of your periods as well as the other symptoms you have will often be enough to diagnose the uterine fibroids. If your medical history is not enough, then you might need to undergo a pelvic exam.
- Pelvic ultrasound: An ultrasound is when high-intensity sound waves are used to produce images of the pelvic area. This is only done when a pelvic exam and your medical history are not enough to diagnose uterine fibroids. If you wish to discuss any specific problem, you can consult a general surgeon.
Fibroid tumour is the abnormal cell growth in the uterus and they are mostly benign. Fibroids usually affect women in the age bracket of 30 - 40. Fibroid tumours are of three types, depending on their location:
- Submucosal fibroids: The tumour develops under the lining of the uterus
- Intramural fibroids: The growth is found amongst the muscles in the wall of the uterus
- Subserosal fibroids: The growth develops on the wall of the uterus right in the pelvic cavity
Causes behind it
The exact cause of fibroids in not known clearly. But certain factors have been discovered that might influence their formation. These factors include:
- Hormones: Progesterone and estrogen are the hormones responsible for recreating the uterine lining during every menstrual cycle. These hormones might trigger the formation of tumour.
- Family history: If any member in your family; your mother, grandmother or sister has/had fibroids in their uterus, you may also develop it.
- Pregnancy: Your body produces excessive progesterone and estrogen when you are pregnant, which may cause an increase in the size of a pre-existing small fibroid. Myomectomy can be done by giving incision on the abdomen or by laparoscopy depending on the size and location of the fibroids.
Signs You are suffering from it
- Heavy bleeding along with blood clots during or between your periods
- Lower back or pelvic pain
- Elevated menstrual cramping
- Frequent urination
- Pain during sex
- Longer than normal periods
- Bloating or pressure in lower abdomen
- Enlargement or swelling of the abdomen
How it can be treated?
Your doctor will formulate the right treatment depending on your age, the mass of the fibroids and your overall health. Your doctor may choose a combination of treatment to cure your fibroids, and they include:
- Medication: Gonadotropin releasing hormones (GnRH) agonists, birth control pills and ibuprofen (anti-inflammatory medicine) are prescribed. GnRH agonists reduce the level of progesterone and estrogen in your uterus.
- Surgery: Myomectomy and hysterectomy are two common surgical procedures to treat fibroids. Myomectomy is performed by removing the fibroids only by making an incision on the abdomen. But hysterectomy completely removes the uterus. The latter is reserved for serious cases.
- Non-invasive surgery: Forced ultrasound surgery, myolysis (shrinking fibroids with laser or electric current), cryomyolysis (fibroids are frozen) and endometrial ablation (an instrument uses heat, hot water, microwaves or electric current to destroy fibroids) are some non-invasive surgical procedures. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.
Breast cancer is a type of a cancerous infection that develops in the skin cells of the breast. This condition is more commonly diagnosed after you have skin cancer and is more common in women than men. There are certain signs to identify this disease, which are as follows.
1. Breast lumps - Lumps are patches of skin that occur due to the thickening and swelling of the skin. Breast lumps is a very common phenomenon for women but that does not always lead to a breast cancer; however, frequent and reoccurring instances of the same increases the risk of breast cancer. A breast lump is easily identifiable through the naked eye as it looks different from the surrounding tissues.
2. Blood discharge - The nipple is one of the most sensitive areas in the human body. In case of women, it is meant to emit milk during pregnancy, in order to feed the infant externally. A probable symptom of breast cancer can also be a frequent discharge of blood from the nipple without any visible damage or injury.
3. Breast changes - If you are experiencing any visible changes in the size, appearance or shape of the breast, then it is an indicative sign that you may have breast cancer. Thus, it is of paramount importance that you observe, touch and physically examine your breast regularly for changes. If there is any major change detected then it is advisable to consult a doctor.
4. Inverted nipple - The tip of the nipple is generally bulging and pointing outwards both in cases of men and women. But sometimes the tip of the nipple is pushed inside due to excessive suction caused by the skin tissues present inside the breast around the nipple area. This suction forces the nipple to grow inwards which is abnormal and might harm the breast and skin in various ways.
However, apart from these main symptoms, some other signs are also there that increase your chances of being diagnosed with breast cancer. They are redness or pitting of the skin over your breast like an orange, peeling or scaling of the pigmented area around the nipple, dimpling of the skin on the breasts, and such others. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
Breast cancer is a type of cancer which occurs due to the development of cancerous cells in a person's breasts. Women are usually affected by breast cancer and breast cancer is one of the most common forms of cancer after skin cancer. Usually fatal if not diagnosed in its early stage, breast cancer is a very serious medical ailment. Read on more to find all about the different symptoms, causes, preventive measures and treatment of breast cancer.
Breast cancer has a few distinct characteristics and if you have a few or all the following symptoms you could be more likely to suffer from breast cancer.
- The formation of a lump in your breast which is different from the surrounding tissue and usually more thickened.
- The discharge of bloody fluid material from the nipples.
- Sudden change of the size, shape and appearance of the breast.
- Certain distinct changes to the skin over the breast for example an indentation in the skin similar to that of a dimple.
- Appearance of an extra nipple which is inverted.
- If the darkened area around the nipples known as the areola is flaking or peeling off.
Studies and researches remain inconclusive on what causes breast cancer. Breast cancer occurs due to abnormal division of the cells located in the breast which over time accumulate and form lumps. They
might spread to other parts of the body. Breast cancer is caused mainly due to a complex interaction of personal genetics, environment and lifestyle choices. Breast cancer can also be caused due to genetics as about 5% to 10% of cases are due to gene mutations which pass onto generations.
There are certain factors which increase the probability of contracting breast cancer. Increasing age, personal and family history of breast cancer, obesity, radiation exposure, pregnancy at an older age, post-menopausal hormone therapy are some of the factors that increase the chances of breast cancer.
Several forms of surgical methods exist to treat breast cancer. Depending on the condition and spread of the disease a suitable surgery is performed. These include mastectomy, lumpectomy, axillary lymph node dissection and removal of both breasts. Other forms of treatment include chemotherapy or the use of high doses of drugs to destroy cancerous cells. Radiation therapy where X-rays are used to destroy the cancer cells is also effective. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
When the skin of a breast looks uneven, it is known as a dimpled skin. Sometimes the skin might appear to be red or inflamed. In this condition, the breast tissue gets affected and this can be a serious sign of concern for cancer. Moreover, this sign is hard to detect on your own. Usually when the sign occurs, it only occurs in one of the breasts. If a woman has it in both the breasts, then likely that it has not been caused by cancer.
Causes of breast cancer dimpling are as follows
1. Advanced breast cancer
2. Breast abscess: A hollow space in the breast that is filled with pus and is at times surrounded by an inflamed tissue.
3. Duct obstruction: The ducts that carry the milk from the nipple are obstructed causing rapid abnormal growth and functioning of the cells present in the breasts causing cancer.
4. Fat necrosis: In this condition, the neutral fats are split into glycerol and fatty acids because the adipose tissue tends to degenerate.
5. Inflammation: Inflammation in the fatty tissue of the breast
6. Mastitis: The breast tissue tends to swell up and get infected. This happens because of the bacteria that enter the breasts through the nipple and this may cause infection in the milk glands.
7. Genetic: Carrying the faulty gene is one of the main reasons why many women end up literally inheriting breast cancer. This can usually be tested with a mammography, especially if one has a history of breast cancer in the family. Yet, one must remember that it is not advisable to take this test too many times as it puts you at risk of contracting breast cancer even if you do not have it, when there is repeated exposure.
First, the doctor might perform certain tests to diagnose and determine the problem. Tests like an ultrasound, MRI or even a mammogram might be used. Depending on what the diagnoses is, the doctor might even want to perform a biopsy. In case breast cancer is diagnosed, there are certain treatments that are available. These include:
- Surgery: The cancerous tissue is removed from the breast or at times when the tissue is too big, the entire breast might have to be removed.
- Chemotherapy: Chemotherapy is a medication that uses a method to send fluids that tend to kill the cancerous cells or prevent them from growing. It is a three to four hour long session at times.
- Radiation: High beam x-rays are used in order to target and destroy the cancer cells present in the breasts.
- Hormonal therapy: In this treatment, the hormones that fuel the growth of cancerous cells are blocked either through medications or surgically. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
Hello meine last year neck k 2 ct scan bhi krwaye the report normal h aur kisi karan last year bahut depressed bhi thi aur roti rehti thi. Kya in sabse breast cancer ka risk increase hota h kya please provide me accurate answer.
Hello sir. I have lower back pain since 2 months back. I have done mri there is disk problem. What is permanent solution is surgery kindly help me.
Hi doctor. I have a severe backache as per Dr. Advice I have done mri. My mri report is as under kindly advise in matter degenerative lumber spondylitis are seen in the form of marginal osteophytes and multilevel disc dessication. 1. D12-l1 & l1-l2 discs show mild bulge, indenting anterior thecal sac without significant never root compression 2. L2-l3 disc reveals right paracentral disc extrusion, indenting anterior thecal sac and causing right lateral recess narrowing, impinging on right traversing l3 nerve root. 3. L3-l4 disc shows mild diffuse disc protrusion, indenting anterior thecal sac and causing bilateral mild neural foraminal narrowing, minimally abutting bilateraltraversing l4 nerve roots. 4. L4-l5 disc reveals mild diffuse disc protrusion, indenting anterior thecal sac and causing bilateral mild neural foraminal narrowing, minimally abutting right existing l4 nerve root-bilateral traversing l5 nerve roots. Nerve roots. Cord is seen ending at d11 vertebral level. Distal cord and conus appear normal. Both hip and si joints are normal. No pre / paravertebral, epidural soft tissue or haematoma is seen.

Breast cancer(स्तन कैंसर) is on the rise in india. Surveys show that every 4 out of 5 Indian women who have breast cancer, suffer from an advanced stage of the disease by the time they reach the doctor. Urban women are at two times more risk of being diagnosed with breast cancer than rural women. Being overweight, eating unhealthy food, and consuming excessive alcohol or tobacco are some of causes that can make you susceptible to this disease.
How you can avoid breast cancer?
- Every woman should do a self-breast examination every month after the periods. You should check for any abnormal lump, change in skin texture or any abnormal discharge from the nipples. Any abnormality above aspects should be promptly investigated by a doctor's appointment, and an ultrasound or Mammography, as required.
- Apart from self-examining your breasts every month for a lump, going for a mammography (an X-Ray of the breast) is vital for early detection of the problem.
- Consult a gynaecologist before going for the test as its frequency depends on your age and risk factor. About 80-90% of tumours can be traced through this screening.
Breast cancer may run in family. If there is no family history of breast cancer, you start doing mammogram at 40 yrs of age but if there is a family history you start even earlier as advised by your gynaecologist.
The symptoms caused due to herniated disc can be very severe and can also cause a bit of disability. The disc of the spine is like a cushion and separates the set of bones on the backside. The discs are shock absorbers of the spine and are mainly composed of 2 parts, a soft jelly centre called the nucleus and a tough outer covering called the annulus.
Effects of Herniated Disk
A herniated or cracked disc is a severe condition and it seems to happen most commonly in the lower back. It happens when a fraction of the soft centre gets pushed through the destabilized area due to degeneration, trauma or by putting pressure on the spinal cord.
Nerves are located precisely at the back of every disc and are responsible for controlling everything in our body. While a disc gets herniated, the external covering of the disc tears and creates a bulge. The soft jelly gets shifted from the centre of the disk to the region where the damage has occurred on the disc. Most commonly, the bulge occurs in areas where the nerve is located and it causes strain on the affected nerve. It has been observed that individuals do not feel any painful sensations even if their disc gets damaged.
When is Surgery Recommended for Herniated Disc?
Surgery for herniated disc is recommended only after options like steroid injections, pain relievers, exercise and non-steroid anti-inflammatory drugs do not work. If the pain persists even after these options, then it becomes important to go for surgery. There are certain risks involved in this surgery like infection, bleeding or nerve damage.
There are chances that the disc may get ruptured again if it is not removed. If you are a patient suffering from degenerative disc disease, then there are chances that problem occurs in other discs. It is very important that a patient maintains healthy weight to prevent any further complications.
The main factor that increases the risk of herniated disc is excess body weight, which causes a lot of stress on the lower back. A few people become heir to a tendency of developing this condition. Even individuals with physically demanding jobs are prone to this condition.
Activities like bending sideways, pushing, twisting, repetitive lifting can increase the risk of a herniated disk. At times, emergency surgery is also required to avoid paralysis in a patient. If you wish to discuss about any specific problem, you can consult an orthopedist.

Effects of Herniated Disk
A herniated or cracked disc is a severe condition and it seems to happen most commonly in the lower back or neck. It happens when a fraction of the soft centre gets pushed through the destabilized area due to degeneration, trauma or by putting pressure on the spinal column.
Nerves located at the back of every disc are responsible for transmitting pain, motor impulse, bladder control etc. in our body. While a disc gets herniated, the external covering of the disc tears and creates a bulge. The soft jelly gets shifted from the centre of the disk to the region where the damage has occurred on the disc. Most commonly, the bulge occurs in areas where the nerve is located and it causes strain and irritation of the affected nerve. It has been observed that individuals may or may not feel any painful sensations even if their disc gets damaged. Other symptoms may be weakness of muscle groups or difficulty in controlling the bladder.
When is surgery recommended for herniated disc?
Surgery for herniated disc is recommended only after options like rest and pain relievers do not work. If the pain persists even after these options, then it becomes important to go for surgery. Surgery is also considered early if there is weakness of muscle groups or acute problem in bladder control. At times, emergency surgery is also required to avoid paralysis in a patient.
However, there are certain risks involved in this surgery like infection, bleeding or nerve damage. There are chances that the leftover disc may bulge out again. If you are a patient suffering from degenerative disc disease, then there are chances that problem occurs in other discs. It is very important that a patient maintains healthy weight to prevent any further complications.

What is Bone cancer?
Bone cancer is malignant tumour of the bones which can spread to lungs or other parts of the body. It may have arisen primarily from the bone itself (primary bone cancer) or more commonly, may have spread to the bones (secondary bone cancer) from cancer of some other body organ like Breast cancer, Prostate cancer etc.
Primary bone cancer usually occurs in growing children and young adolescents, whereas, secondary bone cancer usually occurs in older age group. Usually, the patient experiences pain in the affected area, which over the time, gets worse and continuous. There may also be swelling in the involved region. It can cause weakening of bones resulting in fracture. Some patients may attribute these symptoms to any prior antecedent trauma. Unintentional weight loss may also be seen. Sometimes, these patients are wrongly being treated for infection, thus delaying the correct treatment which may have a bearing on the final outcome.
How common is bone cancer?
Secondary bone cancer is the most common type of bone cancer with bone being the third most common site of cancer spread (metastasis) from other organs. However, primary bone cancers are rare accounting for less than 1% of all cancers.
Causes of bone cancer?
There are no known environmental or other hereditary factors which cause bone cancer, however, certain patients are at a greater risk for bone cancer which include:
- Patients who have received prior radiation therapy
- Patients with a history of Paget’s Disease
- Patients with hereditary retinoblastoma - a type of eye cancer that most commonly affects very young children
- Patients with Li-Fraumeni syndrome - a rare genetic condition
How is it diagnosed?
A patient suspected with bone cancer needs to be investigated thoroughly with blood tests, Xrays, MRI to look for local extent of disease. Since bone cancer can spread to lungs and other bones, staging of the disease is done either with whole body PET CT or a bone scan with CT Chest. Alongwith that, a biopsy (usually with a needle) is required to establish the diagnosis. It’s important to do biopsy from the correct site since wrong biopsy site can be detrimental in limb salvage and can result in amputation (cutting the limb). Therefore, it’s recommended that the biopsy should always be done by the surgeon (Orthopaedic Oncologist) who will be doing the final surgery for bone cancer.
Treatment of bone cancer is a multidisciplinary approach requiring an Orthopaedic Oncologist (Bone & Soft tissue tumour specialist), Medical Oncologist (Chemotherapy Specialist), Radiation Oncologist (Radiotherapy specialist) and Pathologist (Specialist in tissue diagnosis).
Usually in primary bone cancers, chemotherapy is given to the patient followed by surgery to remove the diseased bone which is further followed by adjuvant chemotherapy. Limb salvage surgery is possible nowadays for bone cancers in which the part of the bone involved with tumour is removed surgically (rather than cutting the whole limb) and the defect is reconstructed with artificial joint, thereby saving the limb. In some cases, the cancerous bone so removed is given very high dose of radiation so as to kill all the cancer cells and the sterilised bone so formed is fixed back to the parent bone with the help of plates and screws, a technique commonly called as Extra Corporeal Radiation Therapy (ECRT). In children, since the artificial joint will not grow as the child grows leading to unequal limb lengths over a period of time, the defect can be reconstructed with expandable joint which can be lengthened as the child grows which allows to maintain limb length equality at the time of skeletal maturity.
Is cure possible in bone cancer?
With the current chemotherapy regimes and advanced surgical technology, cure is possible in upto 70-75% patients with primary bone cancer. In patients with secondary bone cancer, cure can still be achieved depending upon the primary cancer and the extent of disease. In advanced cases also, a lot can be done to control the disease and give a quality of life to the patient.
Is it possible to prevent bone cancer?
Since the exact cause of bone cancer is not known, as of now it’s not possible to prevent bone cancer.
Whom to consult?
First chance is the best chance when it comes to curing bone cancers. So, it’s advisable to seek treatment from a trained Orthopaedic Oncologist when confronted with a bone cancer to achieve maximum beneficial outcome.
While you cannot cure breast diseases, family history and maturing, but there are some hazards or risks that you can control. Keeping in mind the fact that there is no certain approach to forestall breast cancer, there are things you can do that may bring down the hazard. Here are five approaches to ensure your breast's well-being:
- Watch your weight: Being overweight or hefty expands breast cancer chances. This is particularly true after menopause and for women who have put on weight as grown-ups. After menopause, the vast majority of your estrogen originates from fat tissue. Having more fat tissue can heighten your chances of getting breast cancer by raising the estrogen levels. Additionally, women who are overweight have a tendency to have more elevated amounts of insulin, than other hormones. Higher insulin levels have been associated with a few tumors, including breast cancer.
- Exercise routinely: Many reviews have found that exercise is the sign of having a healthy breast. Studies show that one to two hours of energetic walking each week, lessened a woman’s cancer risk by eighteen percent. Walking ten hours seven days decreased the hazard all the more.
- Constrain liquor: Women who have two to five mixed beverages every day have a higher danger of breast cancer than women who have just one drink a day or none . As much as three to six glasses of wine seven days have been found to somewhat increase breast cancer chances. It is not clear how or why liquor raises the hazard. In any case, constraining liquor is particularly essential for women who have other hazard variables for breast cancer, like, breast cancer running in their families.
- Restrain time spent sitting: Research has shown that sitting time, regardless of how much exercise you get when you are not sitting, increases the probability of growing cancer, particularly for women. Women who sit six hours or more a day outside of work have a ten percent more serious risk for breast cancer compared to the ladies who sit under three hours a day, and an increased hazard for other cancer types as well.
- Stay away from or confine hormone substitution treatment: Hormone Replacement Treatment (HRT) was utilized frequently in the past to control night sweats, hot flashes, and other troublesome manifestations of menopause. In any case, specialists now realize that postmenopausal ladies who take a blend of estrogen and progestin might probably create breast tumors or cancer. Breast cancer disease seems to come back within five years in the wake of ceasing the blend of hormones. Therefore, get a breast cancer test even if you feel a small lump. If you wish to discuss about any specific problem, you can consult a gynaecologist.
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? it’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the encyclopedia britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1, 000 terabytes. The national archives of britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your i. q. The more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on tv. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
