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.

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.
The signals received may cause the neuron to initiate an action potential (an electrochemical signal or nerve impulse) which is sent along its axon to the axon terminal, to connect with the dendrites or with the cell body of another neuron.

A command neuron is a special type of identified neuron, defined as a neuron that is capable of driving a specific behavior individually. [37] Such neurons appear most commonly in the fast escape systems of various species—the squid giant axon and squid giant synapse , used for pioneering experiments in neurophysiology because of their ...

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.
