Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.
Detailed explanation-2: -The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
Detailed explanation-3: -The nervous system is made up of neurons, the specialized cells that can receive and transmit chemical or electrical signals, and glia, the cells that provide support functions for the neurons.
