You re heartbeat is quickening and muscular movements are enabling your hand to find popcorn etc. your nervous system consists of living tissue composed of cells. these cells fall into 2 major categories the glia & neurons. neurons: cells in the nervous system that receive, integrate and transmit information.

A small part carries messages form the nervous system to the muscles that move the body. soma/cell body: contains the cell nucleus and much of the chemical machinery common to most cells. the branched feelers like structures are called dendrites.
