The human being is considered to be the ultimate form of life on the.
This is not because the human body is strong and agile. Many other.
animals posses skills much superior to humans and are able to perform feats.
humans can only dream of. The one thing that distinguishes humans from all.
of the other organisms on this planet is the brain. The brain is the site.
that controls the human body. However, unlike in animals, in man, the brain.
is also the site of the mind. The mind gives humans superiority over other.
creatures. It provides humans with the ability to reason, to feel and to.
adapt. Because of this, man has achieved so much, and has also realized.
that much more is still ahead.
During the course of evolution, ever since early Homo sapiens and his.
ancestors walked on the surface of the earth, man has wondered about.
himself, and how he relates to the natural world. People learned and.
adapted to new lifestyles. As time passed, humans learned to record.
history. They analyzed past events and applied this knowledge to solve.
problems. These processes improved as more and more people supplied their.
experiences to the common pool of knowledge. Such co-operation created the.
modern man with his superb ability to think.
Many sciences were born. Some of them centered around humans. They.
included, among many others, psychology and neurology. While psychology.
deals with the mind and human behavior, neurology is the study of the.
nervous system.
The nervous system of the human being consists of several parts. The.
main structures are the brain and the spinal chord. The system also.
includes nerves which sense external and internal stimuli and then relate.
all information to the central processing unit, i.e. the brain.
Because of man's rapid evolution in technology and medicine, humans now.
know a great deal more about their own nervous system then they did even a.
few years ago. This increase in knowledge is partly due to the recent.
