Where are your nerves?

Nerves - your nerves are spread all over your body. The organs of the body are composed of tissues. These in turn consist of microscopic units called cells, specialized to perform particular functions such as secretion (glands), contraction (muscles) or conduction (nerves). Likewise the tissue that pick up our nervous system are composed of billions of individual cells located all over the human body. No part of our body is completely insensitive to pain or some other sensation, because nerves are to be found in every part of the human anatomy. The nervous system is usually considered to have two parts, the peripheral or outside system, which is in direct contact with the things that cause pain or pleasure, and the central system, consisting of the brain and the spinal cord. It is in our central nervous system that all our sensations and reactions are finally registered.
