A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.They are located in the brain and spinal cord and help to receive and conduct impulses.
Bumped into this at COM:FPC. Clear, technically precise and encyclopedic SVG diagram of a neuron cell. Articles this image appears in Dendrite, Chemical synapse Creator LadyofHats. Discussion of the diagram: Support as nominator — MER-C 04:51, 13 July 2007 (UTC) Support I have a slight preference for the numbered version though.
A reconstruction of a pyramidal cell. Soma and dendrites are labeled in red, axon arbor in blue. (1) Soma, (2) Basal dendrite, (3) Apical dendrite, (4) Axon, (5) Collateral axon. One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named.
There are many types of neuron, and several types of glial cell. Neurons are the excitable cells of the brain that function by communicating with other neurons and interneurons (via synapses), in neural circuits and larger brain networks.
[citation needed] It can also be altered by hormonal stimulation of the neuron, or by second messenger effects of neurotransmitters. [citation needed] The axon hillock also delineates separate membrane domains between the cell body and axon. [4] This allows for localization of membrane proteins to either the axonal or somal side of the cell.
