nerve cell (neuron(e))

(redirected from nerve cell neurone)

nerve cell (neuron(e))

the structural unit of the nervous system. Each consists of a cell body with a great many fine short extensions from its surface (dendrites) and a long thin extension, the nerve fibre with an axon at its core. Other neurons which influence the activity of the cell (by excitation or inhibition) form synapses on the cell body or dendrites, and the axon terminates at a synapse on another neuron or on the effector which it innervates. See also motor neuron, neurotransmitter.
