neurone


neurone
= nerve cell; n.
one of the basic functional units of the nervous system: a cell specialized to transmit electrical nerve impulses and so carry information from one part of the body to another (see illustration). Each neurone has an enlarged portion, the cell body (perikaryon), containing the nucleus; from the body extend several processes (dendrites) through which impulses enter from their branches. A longer process, the nerve fibre (see axon), extends outwards and carries impulses away from the cell body. This is normally unbranched except at the nerve ending. The point of contact of one neurone with another is known as a synapse.
