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.
A Pap Smear is a screening test done to to test for occurrence of uterine cancer. Carried out in a quick and simple way to extract a sample, the sample is collected from the cervix area of a woman during a pelvic exam. The examination of the sample takes place under a microscope thereafter to find abnormalities that can point towards cancer and pre cancer changes.
There are many reasons why women should get a pap smear screening done:
1. Women who are HIV positive should get this test done regularly so as to detect any anomalies in the cervix. This condition usually comes with higher risk of infections and cancer, which is why regular screening is required.
2. Age is also another factor and women over the age of 30 should go through an annual screening on a compulsory basis. This is also true for women who have been through pregnancy and child birth.
Preparing for a Pap Smear: To prepare for a pap smear test, you need to ensure that you are not menstruating at the time. Also, you may want to avoid sexual activity just before the test so as to get the most accurate readings. During the process, remember to stay calm and relax your body physically.
Procedure: The pap smear procedure is a quick one that might be only slightly uncomfortable. This test is usually carried out on the examination table at the gynecologist's clinic. The legs will need to be spread and placed in stirrups. The doctor will insert a speculum to hold open the vaginal opening so that the spatula can be inserted easily to take a sample from the area. This sample of the cells will be tested in a lab after due preservation.
Test Results: The test results can either be normal or abnormal. An abnormal result does not point at the presence of cancer. Rather it can simply mean that abnormal cells exist in the cervix. The doctor may ask you to go through these tests and screening more frequently so as to study the anomalies in a more detailed manner.
Sir I have slip disk problem in l4 l5 Vert disk and pain in lower spine and pain goes to leg randomly both legs. This is from last 6 months What is easiest way to solve this problem.
I have been diagonosed for Lumber region disc displacement/compression in L1-L2-L3-L4.Though I have been taking homeo medicine for past 8-9 months, the pain subsidise for some days but comes back again at lower back and down the right leg thighs,knee and calf muscles.

Extracorporeal Shock Wave Therapy (ESWT) is a highly effective and innovative treatment option in a variety of fields, from urology to cosmetology including orthopedics. This is a non-invasive method that employs high-energy shockwaves to bring about the healing of the affected tissues. It has been found to provide good results for recalcitrant orthopaedic problems like frozen shoulder to certain chronic degenerative or tendon conditions such as Achilles tendinitis (injury of the Achilles' tendon due to overuse) and plantar fasciitis in heel pain.
How does it work?
The procedure is basically an outpatient/ daycare job. It involves the application of a non-invasive probe to the affected tissue. This is followed by the external generation of shockwaves focused on the target area. The shockwaves cause a force to be created that brings about healing. Although it's still not clear as to why this kind of therapy works, the dominant understanding is that shockwaves render an improvement in the flow of blood so as to promote the body to fix and heal itself.
Depending on individual cases, high or low energy waves may be employed. While pain may occur during the transmission of high energy waves and would require short general anaesthesia, low-energy ESWT is carried out without anesthesia.
What problems can this form of therapy effectively tackle?
ESWT can be used to treat a number of musculoskeletal disorders. From plantar fasciitis (heel pain), tennis elbow, shoulder rotator cuff, degenerated tendons (Achilles' tendon) to hip and knee pain, the therapy has been found to reduce pain as well as accelerate healing in individuals.
Complications are very few and far between with this therapy. Individuals who suffer from hypersensitivity or poor sensation in the affected area are usually not recommended this procedure. Even individuals with heart conditions, seizures and open sores need to consult a doctor before going forward with the therapy.
The therapy has also been found to be very effective in bone healing as well as treatment of bone necrosis (a disease that occurs due to permanent or temporary loss of blood flow to the bones). Additionally in place of surgery, ESWT may also be a valuable option for non-healing fractures.
I am 33 and my body has became very stiff due to no physical exercise. I have slip disk and neck ailments. Also mental tension getting worse. But need to come over this. What could be the starter guidelines for getting started with Yoga/Meditation.
This is a form of epithelial cancer and is a lose called eating cancer
Symptoms:- it first appears on the nose as a hard, dusky red sore and spreads in ulcerative form destroying the tissues till the bones are exposed. This affect women 10 time more than men. It usually appears in women between the age. Nausea, vomiting and abdominal pain may accompany. It is an ulcerative skin disease and requires a very long-term treatment. Sensitivity to sunlight is usually present. Lupus is caused by disruption of body waste disposal system from failure of special enzyme d nasil, which fails to remove wastes from the body.
The disease is easily noticeable as it is outside the body on the the skin and biopsy is performed to confirm it.
If possible, the affected portion of the body is cut out.
I suggest homoeo doctor consult and homoeo treatment best.

I am suffering from slip disc l4 l5 problem from last 5 yrs. I have tried all the treatment. But. please provide some tips.
Breast Cancer - What exactly is it?
‘Breast cancer’ is a term that is used to refer to a malignant tumour, which has developed from cells present in the breast. Generally, all tumours can be divided into two categories i.e. benign and malignant and it is the malignant tumour that is responsible for causing cancer. Breast cancer generally originates in the cells the milk producing glands of the breast's or the passage, which carries milk from the glands to the lobules. Additionally, breast cancer can also originate in the stromal tissues, including the fibrous and fatty connective breast tissues.
Breast Cancer: Treatment Options
Treatment for breast cancer depends upon two things: the exact type of the cancer and how advanced the cancer is. Treatment options for breast cancer can thus be broadly divided into two categories as Local treatments and Systemic treatments.
Treatments that target the tumour without having any effect on the rest of the body are called local treatments. The following types of local treatment options are available for treating breast cancer:
- Surgery: Surgical breast cancer treatment involves removal of the malignant cancerous tumour in an operation. Smaller tumours can be removed using a surgical process referred to as ‘lumpectomy’, wherein the tumour along with a small amount of healthy tissue surrounding the tumour is removed. For larger tumours, removal of the entire breast becomes mandatory, in a surgical process known as ‘mastectomy’. Women who undergo mastectomy can choose to undergo reconstructive plastic surgery for reconstruction of the removed breast(s).
- Radiation Therapy: This basically involves using radiation to kill cancer cells present in the body. Radiation therapy is a long-drawn process that usually involves a set number of treatments administered over a long period of time. Radiation therapy is also generally the follow-up procedure after a lumpectomy, or more rarely, a mastectomy.
Treatments involving drugs that are administered via either the mouth or direct injection into the bloodstream are called systemic treatments. These include:
- Chemotherapy: This includes using drugs to destroy the cancer cells present in the body by stopping the cancer cells from growing and dividing. Chemotherapy can be administered using either an IV (intravenous) tube or via pills that can be swallowed.
- Hormone Therapy: This treatment option is used for treating tumours which have tested positive for progesterone or oestrogen receptors. Blocking hormones that fuel the tumour’s growth is the basis of this therapy.
- Targeted Therapy: This targets specific proteins and genes which contribute to growth and survival of the cancer cells. Targeted therapy is an extremely focused treatment, and is very effective in blocking the growth and division of cancer cells, as well as minimizing damage to surrounding healthy cells.
