... having more physiological problems which they grow out of, while with older people, stress and substance abuse play a larger role. is most common among children from the ages of 4 to 12. Estimates for the percentage of the population which will sleepwalk at least once in their lifetime range quite a bit. Some sources say that most children will walk in their sleep at least once, with 15% of them more regularly. Others claim that 18% of the population is "prone to ". There is consensus, however, on the fact that boys sleepwalk more frequently than girls and that it is between the ages of 11 and 12 that the most cases of are reported. The fact that most chi ...

... permitting the termination of unwanted pregnancies for medical, social, or private reasons. Abortions at the woman's request were first allowed by the Soviet Union in 1920, followed by Japan and several East European nations after World War II. In the late 1960s liberalized abortion regulations became widespread. The impetus for the change was threefold: (1) infanticide and the high maternal death rate associated with illegal abortions, (2) a rapidly expanding world population, (3) the growing feminist movement. By 1980, countries where abortions were permitted only to save a woman's life contained about 20 percent of the world's population. Countries with moderatel ...
... are unable to stop the growth of cancer cells and this causes the development of a tumor. Whether or not the tumor will be cancerous or not is determined at this point by a process called differentiation. Differentiation is the process by which normal cells undergo physical and structural changes as they develop to form different tissues of the body. Differentiated cells specialize in multiple physiological functions. For example, a highly differentiated cell like a nerve cell still shares many features in common with all cells (i.e. nucleus, cell membrane, and mitochondria). However, microscopically and functionally it is unique from other cell types in the ...
... approve of abortion because they consider that a fetus is not an individual human until birth. Abortion is wrong and it shouldn't be legal. If a doctor killed a baby one minute after it were born, they would be charged with murder. But if they were to kill a baby one minute before it were born, and a minute before that and so on, they would not be considered a murderer. At what minute can one consider life worthless and the next precious? Some people will say that abortion is not a matter of life and death, but medical research proves that the fetus is a living organism. People also argue that a woman has the right to control her body and has the right ...
... at all times, they are payed at very good wages. Human beings have been suffering from disease since they first appeared on the earth about two and one -half million years ago. Throughout most of this time, they knew little about how the human body works or what causes disease. But medicine has gone through many stages throughout history. In prehistoric times, people believed that angry gods or evil spirits caused disease. To cure the sick, the gods had to be pacified or the evil spirits driven from the body. In time, this task became the job of the first "physicians".3 The first - known surgical treatment was an operation called trephining. Trephining in ...
... once, why can't they happen again? Let us take a look at the most horrible, so far, of the plagues: The Black Death. It took Europe by storm from approximately 1345 to 1361. It would also make small comebacks throughout the next 400 years, but never like it did the first time. It also reached into Africa, China, Russia, and the Scandinavian countries. It was truly a worldwide pandemic. But, it has a secondary effect that not many people are aware of. The colonies of Greenland, settled by the Vikings, were stricken by the plague and they soon disappeared. It is known that these colonies kept in contact with "Vinland", which was near New Foundland, in Canada. ...
... symptoms are different from the aura or feeling that precedes a generalized seizure and comes seconds or minutes before the actual seizure. In most people, however, seizure are unpredictable and unrelated to the person’s current situation some external determinants may trigger seizures though. Lack of sleep, emotional stress, missed meals, alcohol ingestion/withdrawal, even fever or some infections may produce seizures. There are many possible cause of but in more than half the causes, the precise cause cannot be determined. An inherited tendency to develop the disorder occurs in the families of some patients. Some of the known cause include head i ...
... it is stored in the tunica interna, the innermost layer, of blood vessels. As it is stored it starts to build up eventually clogging the vessel. As a result of this all cells feed by the vessel die because of a lack of oxygen. If this condition is found early, it can be corrected with surgical procedures or, in some minor cases, corrective procedures. Surgical procedures include bypass, laser and balloon surgery. In bypass surgery a vein is removed from the lower leg and a clogged vessel is worked around. Often in type of surgery the whole mid section of the body is cut and the ribs are pulled back, very painful with a very slow recovery. Some hospitals hav ...
... primitive surgeries were successful is unknown. The earliest way for man to observe the brain was by noticing brain damage to a particular area of the brain that was damaged. Such observations were first recorded some 5,000 years ago (Myers,1995). The most popular case is that of Phineas Gage a railroad worker that had severe frontal lobe damage. This happened when a rail road spike was shot through his head by a piece of dynamite. Miraculously he lived through the experience, but with a severe change in his personality. From this physiologists learned that personality was largely controlled from this point namely by removing a persons inhibitions. Fo ...
