Detailed explanation-1: -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-2: -(nerv sel) A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.

Detailed explanation-3: -Neurons are specialized to transmit information throughout the body. Whereas nerve is a whitish fibre or bundle of fibres in the body made up of number of neuron cells that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs.

Detailed explanation-4: -The central nervous system (which includes the brain and spinal cord) is made up of two basic types of cells: neurons (1) and glia (4) & (6). Glia outnumber neurons in some parts of the brain, but neurons are the key players in the brain.

Detailed explanation-5: -Neurons are one of two major types of nervous system cells. They are electrically excitable cells that transmit nerve impulses. Neuroglia are the other major type of nervous system cells.
