Neurons

A

The basic cells of the nervous system that allow different parts of the body to communicate with each other. The body has billions of neurons carrying nerve impulses throughout the body via an electrochemical process. In the brain, this process creates brain waves. Each neuron consists of a cell body, several dendrites, a single axon, and terminal end fibers
