The Nervous System And The Brain

What Is The Brain?

All your thoughts, feelings, memories, emotions, wishes and dreams happen in one place inside your body, your brain. It’s the place where you are conscious and aware of what’s going on around you. It’s the place where you think, imagine, have ideas, daydream. Your brain is also the control centre for your whole body. It tells your heart to beat, you lungs to breathe air, your stomach to digest food, and it controls hundreds of the other inner body processes. And your brain makes your muscles work, so that you can move around and carry out skilled tasks such as drawing or riding bicycle. The brain can do these amazing jobs because it is connected to all parts of your body, by an incredibly complicated network of nerves. These nerves look like thin pieces of shiny thing. They carry messages, in the form of tiny electrical signals called nerve impulses, between the brain and every other body part.

The brain looks like a giant, wrinkled walnut. It’s most obvious part, making up about nine tenths of its whole size, it called the cerebrum. It is divided into two halves, known as cerebral hemispheres. Each hemisphere is covered by a pink-gray layer known as the cerebral cortex, which is where thinking happens. Under the cortex is a thick white layer, the cerebral medulla. At the rear of the brain is another wrinkled part, but much smaller than the cerebrum. This is known as the cerebellum. At the brain’s base is a narrow part, the brain stem, which tapers into the spinal cord in the upper neck.

The brain fills the top half of the head. It is well protected by the strong skull bones around it. The brain’s base tapers into a long thick nerve called the spinal cord. Nerves branch from the cord and spread out through the body. These peripheral nerves divide and become smaller, and reach every part, even the fingertips and toes.
Different patches or areas of the cortex receive nerve messages from the body’s senses, such as the eyes and ears. These are cortical sensory centers. Another patch of the cortex, the motor area or center, sends out message to the muscles so that the body can move. Continue Reading ...

Toothache Causes

Teeth and the surrounding gum areas can suffer from extreme pain due to several reasons. Known as toothache, this childhood nightmare can affect adults, and as it usually does, toothache comes with no warning. What causes toothache is not limited to poor dental hygiene and can also be due to stress, temperature sensitivity or even as a reaction to a dental procedure.

Common Causes of Toothache

o    Poor dental hygiene. – Forgetting to brush and floss your teeth can directly contribute to plaque build up and tooth decay. Bacteria living and feeding on plaque cause our teeth become weak and susceptible to infections. Brushing helps us steer away from cavities and prevent teeth from deteriorating.

o    Tooth decay. – Dental cavities and open crowns cause toothaches to keep coming back. Food particles can be lodged in between teeth, open crowns and between gum areas which may cause irritation and infection. Gargling a glass of lukewarm water with a teaspoon of salt will help remove the food particles. Also, saline solution helps ease the pain due to its analgesic properties, it numbs the affected area and prevents onset of infection. Continue Reading ...

Fungal Nail Infections

Fungal nail infection, otherwise referred to as ringworm of the nail in layman’s terms, is medically known as Onychomycosis or Tinea Unguium. It is the most common disease affecting human nails and can affect both finger and toenails, but more common on toenails.

Fungal nail infection is usually suspected if ones nails can be broken easily, are thickened, with change in colour, detaching from the nail bed, have increased dirt or debris underneath, with change in shape and loss of their shiny surface. Fungal nails are also often painless, except in very severe cases.
Fungal nail infection, just as the name implies, is caused by infection of the finger or toenails by fungi which are mould-like or yeast-like germs often found naturally on human skin, hair and nails. Some of these fungi hosted on the human body are often useful to the body, but given the right conditions, they can multiply rapidly and cause infections. Fungi thrive well in moist and warm environments, so fungal nail infections occur frequently in people who use public bathrooms, swimming pools, gyms and in people who sweat a lot, especially those who frequently wear tight fitting occlusive footwear (cover shoes). Other factors which increase the risk of developing fungal nail infections include a positive family history of fungal nails, prior trauma or injury to nails, increasing age, reduced immunity (e.g. from HIV or drug use), frequent submersion or hands in water, poor general health and hygiene.
Treatment of fungal nail infection is not very easy as the infection is embedded within the nail, which is quite difficult for drugs to penetrate. The primary aim of treatment is to eradicate the fungi from the nails as demonstrable by microscopy and culture, but this does not guarantee a return of the affected nails to their normal look. However, as the nails grow the abnormal ones are, sometimes, gradually replaced by healthier looking uninfected nails, but this process could take more than a year as nails grow very slowly.

The drug of choice for treatment of fungal nail infection is terbinafine (Lamisil), which is taken orally as a daily 250mg dose for 6-8 weeks in fungal fingernails or 12-16 weeks in fungal toenails. Another alternative drug is griseofulvin (Fulcin), which is also taken orally as a daily 500mg dose for 6-9 months in fungal fingernail infection or 12-18 months in toenail infections. Fulcin is less expensive than Lamisil, but it has to be taken for much longer and the cure rates for Fulcin is also less than that for Lamisil. Other drug choices include oral itraconazole or topical medications (nail paints) containing ciclopirox or amorolfine, which can be applied directly on the infected nails. Sometimes a combination of an oral drug and a nail paint can also be prescribed, but the oral drugs are generally more effective. If treatment fails for one drug, another one could be tried or the nail could even be removed surgically.
A note of warning though, most of these antifungal drugs can cause damage to the liver, harm to an unborn child and many other adverse reactions or drug interactions, so be sure to contact your doctor for a proper prescription before taking them.

Lower Your Cholesterol

The major risk factors for coronary heart disease include smoking, lack of exercise, high blood pressure or hypertension and high blood cholesterol. Smoking has been recognized as a risk factor since the 1950’s. The fact that blood pressure reduction was necessary to cut down the risk of heart disease and a stroke has become the focus of attention since the 1970’s.
The cholesterol story is a comparatively recent one. Although scientists and physicians have suspected high cholesterol to be a risk factor for over forty years, it is only during the past decade or so that results of several scientific studies have already demonstrated a strong relationship between high cholesterol level and heart disease. Furthermore, it has been established by reducing your cholesterol by 1%, you can reduce your risk of heart disease up to 2%. A still remarkable discovery is that you can even reverse the hardening and narrowing of your own coronary arteries through a low fat and low cholesterol diet and other changes in your lifestyle.
The National Institute of Health in United States, for example, found that people with blood cholesterol readings of over 265 mg were, at least, four times more at risk of CHD as compared to those with readings of 190 mg or less. It has been noted that only a very small percentage of people with cholesterol levels below 160 mg have heart attacks. Large population studies have found a definite and a substantial increase in the rate of heart attacks in those with blood pressure readings of 240 mg and over. Your chances of heart attack start rising significantly if your cholesterol rises over 200 mg. High cholesterol, like blood pressure has been termed as Silent Killer, since there are no symptoms of high cholesterol itself.
One day it is possible that your heart may experience lack of oxygen due to insufficient blood supply caused by the slow clogging and blockage of coronary arteries. This is known as atherosclerosis and is due to the deposition of fat and cholesterol in the walls of the arteries. – Small sized pipes that carry blood to the different parts of the body, including the heart. If a major artery leading to heart is completely blocked, this will immediately cut off the blood supply to a part of the heart and cause a heart attack.
The US Food and Drug Administration Department requires that most food items in tins and packets must carry information regarding their nutritional contents. It is a common sight to watch people in the big supermarkets looking very carefully at these tablets. It is only through these steps that the population there has succeeded in lowering the risk of heart disease.

In India, people have lagged behind in their efforts. There are many possible reasons for slowness. Lack of education and resources is a major factor. The scientists and physicians in India have however, attributed the problem of increasing deaths to CHD and high cholesterol. That, of course, is not enough. There is a paramount need to understand the problem of high cholesterol and to do all that is necessary to control high levels of it. We cannot really afford to complacent. It is now well established that a persistently high cholesterol level can almost certainly precipitate a catastrophic event such as heart attack in your life. So the need to take appropriate action is an urgent one. High cholesterol is dangerous for your heart and doing nothing about it may prove to be lethal. You cannot really wait for the government or your own doctor to talk to you about this problem.
Frankly speaking, you have to be in charge of your own health. If you continue to ignore these important matters, you may not even be alive to complain against the government or even your doctor. The ultimate responsibility is for your health is you!
