what part of the nervous system is found throughout the body
Nervous system The nervous system is defined by the presence of a special type of cellâ€”the neuron (sometimes called "neurone" or "nerve cell").[4] Neurons can be distinguished from other cells in a number of ways, but their most fundamental property is that they communicate with other cells via synapses, which are membrane-to-membrane junctions containing molecular machinery that allows rapid transmission of signals, either electrical or chemical.[4] Many types of neuron possess an axon, a protoplasmic protrusion that can extend to distant parts of the body and make thousands of synaptic contacts;[12] axons typically extend throughout the body in bundles called nerves.
