gan·gli·on cell

originally, any nerve cell (neuron); in current usage, a neuron the cell body of which is located outside the limits of the brain and spinal cord, hence forming part of the peripheral nervous system; ganglion cells are either 1) the pseudounipolar cells of the sensory spinal and cranial nerves (sensory ganglia), or 2) the peripheral multipolar motor neurons innervating the viscera (visceral or autonomic ganglia).
Synonym(s): gangliocyte

A neuron the cell body of which is located outside the limits of the brain and spinal cord, hence forming part of the peripheral nervous system; ganglion cells are either 1) the pseudounipolar cells of the sensory spinal and cranial nerves (sensory ganglia), or 2) the peripheral multipolar motor neurons innervating the viscera (visceral or autonomic ganglia).
Synonym(s): gangliocyte.

ganglion cell

1. Any neuron whose cell body is located within a ganglion.
2. A neuron of the retina of the eye whose cell body lies in the ganglion cell layer. The axons of ganglion cells form the optic nerve.
