What Is Nervous Tissue?
Nervous tissue is composed mostly of nerve cells or neurons, which serve
as the basis for an extremely rapid communication system in our body. It
also provides the basis for thinking. The central nervous system includes
the brain and spinal cord and represents the thinking and responsive por-
tion of our nervous tissue. Links of neurons extend from the central ner-
vous system to various organs and tissues in our body, thus allowing the
central nervous system to regulate their function. In addition, links of
neurons extend to our skeletal muscle thereby allowing the central nervous
system to initiate and control our movement. Special neurons function as
sensory receptors and are located in the skin and sensory organs (tongue,
nose, ears, eyes) as well as deeper in tissue inside our body. These receptors
keep the brain informed as to what is going on inside and outside our body.
They register pain and sensation (sight, hearing, taste, smell, and touch)
and relay that information to the brain where it is interpreted.
