PITUITARY

Category : Brain

I am a pinkish, pea-size nubbin of tissue. I hang, like a cherry, on a tiny stem from the underside of your brain. I weigh only about half gram and 85 percent of that is water. But after your brain I am probably the most complex organ in your body. I play a key role in almost everything that you do. The all important hormones that I secrete can work wonders or wreak havoc. I can let you live a perfectly normal existence, I can sicken you with a bizarre spectrum of diseases or I can kill you. It was one of my hormones that gave you the initial push into the world: oxytocin started the contradictions of your mother’s womb. It was I who decided that you should be of normal size, rather than a one meter midget or a two and a half meter giant. I can shrink your sexual organs back to boy size, or so hasten your ageing process that you will be an old man in a few months’ time. I am your pituitary gland.

pit-surgI have been described as your master gland, the conductor of your endocrine symphony. I take my orders straight from that prune size section of your brain called the hypothalamus, from which I hang. It is my job to monitor the activity of other glands, to see that they produce exactly the right amount of their hormones. I suppose you could call me a chemical boss of your body, and I am not bragging when I call myself the Earth’s most compact and intricate chemical plant.

I am divided into two lobes. My small posterior lobe stores two hormones produced by the hypothalamus. My much larger anterior lobe produces approximately ten hormones. These hormones are among the most complex substances known to man. My total daily output, however, is less than1/10,00,000 of a gram.

It took a long time to sneak the first of my secrets from me. For centuries, doctors thought my function an ordinary one. I was believed to be the source of nasal mucus! My elusive secretions were present in far too small quantities to be detected until the advent of modem chemistry. Now they are being found by accumulating large quantities of different animal and human pituitaries. I secrete nine hormones that regulate homeostasis.

One of my hormones manages the thyroid gland in your neck. If I secrete too much of this thyrotropic hormone, thereby setting too fast a pace for the thyroid, you would almost literally bum up. Your appetite would be huge, yet you would remain thin. On the other hand, if I were to produce too little of this hormone, you would be sluggish, puffy, dim-witted. Fortunately, I have a built-in feedback mechanism to prevent either of these things from happening.

Much of the same situation exists with your testicles. I have two hormones, which govern these glands – one by stimulating production of sperm cells 55a4f067d0553dcf6f35969d017fd8c1and male hormone, the other by promoting growth of the duct system to transport the sperm. Incidentally, your wife has identical hormones to nudge along development of her ovaries and production of eggs. Thus, fertility and life depends on me.

For your wife, I normally secrete only enough follicle-stimulating hormone (FSH) and interstitial-cell-stimulating hormone (ICSH) to produce a single mature egg a month. If I were to go on a spree and produce too much FSH and ICSH, five or more eggs might ripen in a single month, and your wife might have quintuplets. It is the same with your testes: too little FSH and ICSH, and you would become nervous, whining and sexually apathetic; too much, and he might well become a snorting bull.

The most pervasive and plentiful of my chemicals is my growth hormone. It played its chief role in your youth, seeing to it that you followed normal growth patterns until your bone ends closed and no further height could be added. But my growth hormone may still have jobs to do for you, even though you may be 47 years old. If you break a bone, it is believed to hasten development of new bone; if you nick yourself with a razor, it is thought to hasten healing. It may well encourage growth of new tissues to replace those that have worn out. If something should happen to make me produce this hormone in excess right now, I am quite capable of doing it, growth would resume in your hands, feet, jaws. A long jaw would sprout; your nose would enlarge into a vast bulb; your hands and feet would grow enormously.

Another pituitary hormone, found only in animals so far, has fascinating possibilities for disease control. This is lipotropin, a hormone that acts as watchdog on fat deposits in the body. It has the striking capacity to move solid fat to the liver, where it is converted into glucose. Thus, if properly harnessed, my lipotropin could well be the answer to that paunch you are beginning to grow, helping to dissolve it and keep you youthfully trim.

pituit1Since I rest in a bony cradle in the center of your head, I am almost perfectly protected from injury. Yet it can happen, and results can be dramatic. Head injury, for example, could lower my production of vasopressin (the anti-diuretic hormone), which acts as a brake on the kidneys. The kidneys would go into high gear in producing urine, perhaps gallons of it a day. To survive, of course, you would have to drink the same amount of water, something you would have no trouble doing since a constant, raging thirst accompanies this condition.

While injury to me is rare, tumors are less so. And the range of effects of these tumors can be startling. Suppose a tumor should cause me to produce too much of the hormone ACTH, which monitors the hormonal activities of the two adrenal glands sitting astride your kidneys. You would develop a great paunch of abdominal fat and another fat pad would appear on your neck and upper back. Your legs would look ridiculously spindly. Blood pressure would soar, sex drive disappear.

Calcium would drain from bones; your spinal vertebrae might collapse. Amid all this wreckage, your heart would labor ever harder, and would eventually give up. To forestall this, doctors might decide to try to slow me down with radiation; or they might remove your adrenal glands. Then, of course, you would have to be dosed with hormones continually.

Migraine Causes
Change in lifestyle:
Modify your lifestyle such that you get complete freedom from the tensions in your life. Pressure on brain should be minimized. It is almost impossible to change the lifestyle, but you may try to get adjusted to the better side of your life.

Reduce salt intake:
Higher salt intake can cause higher blood pressure, which has its repercussions on headache. So, the salt intake should be in control, which leads to lessen in risk of migraine.

Reduce stress:
Reduction of stress can largely decrease the development of  that, so activities such as performing Yoga can reduce stress. There are many other mental activates which can lead to decrease in stress.

Cure for Migraine:
It can be cured by strengthening the nerve cells, providing required proteins for optimizing its communication links and ensuring availability of sufficient oxygen in the blood. The above can be achieved by taking combination of food supplements. Once the migraine is cured, then the supplements may be reduced and the persons may follow the supplements recommended for a healthy person.

Phases : Relief And Cure

Migraine is a neurological disorder, which is mostly confused with headache by people who don’t have correct knowledge about it. Headache can be cured very easily by some mild dose of drug but migraine patients need special care and treatment.

When a person is suffering from migraine, he is in such a condition where he can not perform regular activities for a certain period. They become very much sensitive to light, sound and smell stimuli. Other common symptoms seen are nausea, vomiting and blurred vision. Migraine can last from a few hours to a week time. All the manifestations that can be observed in migraine patients are –

  • Blurred vision
  • Diarrhea
  • Abdominal pain
  • Weakness of the body
  • Vomiting
  • Severe headache
  • Pain in the neck region
  • High temperature
  • Dizziness
  • Sensitivity to sound, light and smell

There are generally foru phases in any kind of disease.The four phases in Migraine-

  1. Prodrome –Early symptom, where development of the condition is prominent. Symptoms such as headache, fever etc. are seen during this phase.
  2. Aura – A kind of disturbance seen in migraine sufferers before the migraine headache. Main symptoms are seen here.
  3. Pain – Headache phase where the actual migraine headache is seen. A high level of headache is prominent here.
  4. Postdrome phase – The final phase of migraine headache.

Migraine is caused by many reasons, mainly –

Exposure to smoke: Smoking or exposure to cigarette smoke is one of the major causes. According to a research,more than 50% of people who gave up smoking became migraine-free.

High stress: High stress periods, and then sudden rest can cause disturbances in the Central nervous system and can cause attacks of headache when resting. Too much sleep after high stress should be avoided to avoid these attacks.

Hormonal fluctuations: This can also be regarded as stress, which is caused by over excitement. During excitement, a high level of adrenaline is secreted and due to this, stress is experienced, and this triggers attacks of headache.

Irregular sleep: Too much or too little sleep is risky to cause migraine atta cks. Long weekend sleeps are pleasant while sleeping, but after the sleep ends, the attacks may start. Regular routine of sleep have to be maintained.

Food habits: There are a lot of food habits that may not suit your body and cause many symptoms ultimately leading to migraine attacks. So a regular balanced diet should be maintained.

How to find relief in migraine?

Relief in migraine by diet:
It is found that following certain migraine diets can provide relief in migraine attacks. This includes eating of whole and natural foods and reducing the intake of processed or cooked foods.]

Reduce certain things in diet:
Things like large amount of caffeine, red wine should be reduced. Along with this, dairy foods, nut products, chocolate, processed meat and alcohol intake should be decreased as they contain chemical addictive which may trigger migraine attacks.

I am you and you are me! Hence I desire to serve you to the best of my ability and to the fullest of my capacity. I am your brain. Compared to me, other wonders of the universe are insignificant.But, I am not just part of you;I am your personality, your reactions, your mental capacity.
Compared to me, other wonders of the universe are insignifi cant. I am a one and a half-kilo mushroom of grey and white tissue of Human brain in x-ray viewgelatinous consistency. No computer exists that can duplicate all my functions. My components are staggering in number: some 30 billion neurons and fi ve to ten ti mes that number of glial cells and all this fitted into the crown of a size 7 hat! I am your Brain.

But, I am not just part of you; I am your personality, your reactions, your mental capacity. You think that you hear with your ears, taste with your tongue and feel with your fingers. All these things happen inside of me – ears, tongue and fingers merely gather information. I tell you when you are sick, when you are hungry; I govern your sex urge, your mood and for that matter everything in you.

Even when you are asleep, I continue to handle traffic that would swamp all the world’s telephone exchanges. The amount of information flooding on you from outside is staggering. How can I cope with it all? I simply select what is important, and ignore the rest. If you switch on a TV and attempt to read at the same ti me, you will concentrate either on TV or the book, but not on both. If you become involved in a particularly good novel, you should not be surprised if you do not remember hearing your favorite program.

Of course, if something potentially dangerous happens, I instantly shift gears. The moment you slip on the ice, I immediately direct you to regain your balance, and then signal your arms to break the fall. Finally, if you hit the ground, I let you know if you are hurt. The event is stored in my memory to warn you to walk carefully on ice in future.

In addition, to taking care of such emergencies, I have thousands of housekeeping chores to perform. For example – overseeing breathing, pumping of the heart, functioning of lever etc….. Sensors inform me that carbon dioxide is rising in your blood and that you need more oxygen. I step up the breathing rate – timing the contraction and relaxation of chest muscles.

In thousands of such ways, I support you and in return, I hardly demand. I just represent only two percent of your body weight but I require 20 percent of the oxygen you inhale and a fifth of the blood your heart pumps. I am utterly dependent on a constant supply. Let there be a temporary shortage and you will faint. Let the supply be cut off for a few minutes and I suffer grave damage– paralysis or even death may result. I also demand a steady supply of nourishment-glucose. Even in situations of acute starvation, I get first preference on any available resource because without me you would die.

In many respects, I am like a vast, unexplored continent, with little more known than the rough outlines of the shore. But, the researchers who are attempting to map me have come up with some fascinating information. For example, although all pain is felt in me, I myself have no pain sensation even when I am cut. Thus, brain surgery is performed with the patient wide-awake, allowing the brain explorers to stimulate specific areas of me electrically and observe the response. If you ever undergo such surgery, you will be amazed at what can happen. A tickle of electricity in one place and you might see a long-forgotten teacher who taught you in class-II. Stimulated in other places, you might hear a train whistle or a recitation of nursery rhyme you could not have recalled a few hours earlier. I am like an old attic containing mementos of a lifetime. You might not be aware of what it is in the attic, but it is there.

The brain mapping researchers have at least a rough outline of my primary functioning areas: vision in the rear, hearing on the sides. Perhaps the most interesting discovery is the “pleasure center.” Teach a monkey to press a switch that gives a minute electrical prod to the “pleasure center” and the animal will press the switch almost continuously– preferring the stimulation even to food. Given time, it could die of starvation presumably happily. If you ever suffer a severe depression, doctors might implant such an electrode in your brain. Little pits.

of electricity could transform a depressed you into a delighted you. I normally feel happy when I am in a higher excited state. I fail to understand, that whenever I am under depression the drugs administered to me are the suppressants.

I reside, of course, in a well-protected fortress. The skull is about half a centimeter thick at the top, and even thicker at the base. I am bathed in a watery fluid that cushions me from shocks. A ‘blood-brain barrier’ serves as a gatekeeper letting some things in, denying entrance to others. Thus, it welcomes the glucose I need, but blocks out bacteria and toxic substances. Most painkillers, anesthetics, alcohol and hallucinogenic drugs, that wildly distort my normal activities pass in with ease.

A word about my architecture. Lift a piece of grass from a lawn and note the baffling intertwining of roots. I am something like that–multiplied by millions. Each of my 30 billion nerve cells, or neurons, connects with others–some as many as 64000 times!

A neuron looks something like a spider attached to a filament. The spider is the cell body, the filament the axon, the legs the dendrites. The legs pick up a signal from adjacent neurons, pass it to the body; the signal is in turn passed along by the filament at speeds up to 340 km/h. After each signal passes, it takes the filament about 1/2000 of a second to recharge itself chemically. At no point does one of my neurons touch another; signals are passed spark-gap fashion. At each “firing” one nerve chemically communicates with another.

For all my versatility, I unfortunately never learned the wonders of reproduction. Skin, liver tissue, blood cells can be replaced after damage or loss. But if I lose one of my cells it is lost forever–and by age 35, you loose over 1000 of my nerve cells a day! With age, I also lose weight but for my great reserves, these things might be disastrous. But I compensate. Let a thousand cells die and a thousand others may never notice the loss. But, if enough cells are destroyed, you may. Your sense of smell might diminish. Your taste could become less acute and hearing fade. You might notice your attention span diminishing, and you might have more difficulty remembering names, dates, and telephone numbers. But I will take care of the really important jobs to the end.

You know that you have two kidneys, two lungs, two adrenals. You do not think of me as a “paired” organ, but in a sense I am, in that I have distinct right and left hemispheres. My left half controls much of the activity on the right side of your body, my other hemisphere the left. With right-handed people, the left hemisphere is dominant. With Lefties, the reverse is true. Recent studies suggest that my left hemisphere controls my ability to walk, write and do mathematics. My right hemisphere is essentially mute but can do other things, such as make special judgments.
