Comment: The featured synapse is shown on the cell body - which strikes me as very unusual. Debivort 05:56, 13 July 2007 (UTC) Probably from the angle the image is drawn, which is why the synapse is magnified to show that there is a very tiny gap between the synapse and cell.
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.
The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1] 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 ...

It contains parasympathetic pre-ganglionic neuron cell bodies that synapse in the ciliary ganglion. [ 3 ] [ 2 ] It contributes the autonomic, parasympathetic component to the oculomotor nerve (CN III), [ 4 ] ultimately providing innervation to the iris sphincter muscle and ciliary muscle to mediate the pupillary light reflex and accommodation ...
A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber. [1] It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction. [2] Muscles require innervation to function—and even just to maintain muscle tone, avoiding atrophy.
