What is the function of the Nervous System?
This vital system enables us to percieve many of the changes that take place in our external and internal environments and to respond to those changes (seeing, hearing, tasting, smelling and touching are examples of perception). It enables us to think, reason, remember and carry out other abstract activities. It makes possible body movements by skeletal muscles, by supplying them with nerve impulses that cause contraction. It works closely with endocrine glands, correlating and integrating body functions such as digestion and reprodution.
