Anatomy and Physiology: An Introduction : The Nervous System
(ONLINE)

This lesson provides a glimpse into the human neural network we call the nervous system. We can compare the nervous system to a highly complicated computer network. If we think of the brain as that central processing unit, or the command centre, we can visualize a complex network of nerves and organs emanating from it. The network monitors the internal and external environment and sends information about those conditions to the brain, which in turn processes the information and sends signals back to the rest of the body to perform an action or to regulate body functions.
