Neuron

A neuron^[1] (or neurone) is a nerve cell that carries electrical impulses.^[2] Neurons are the basic units of our nervous system.

Neurons have a cell body (soma or cyton), dendrites and an axon.^[2] Dendrites and axons are nerve fibers. There are about 86 billion neurons in the human brain. Almost all brain cells are neurons. The human brain has about 16 billion neurons in the cerebral cortex. The neurons are supported by glial cells and astrocytes.[1]

Neurons are connected to one another, but they do not actually touch each other. Instead they have tiny gaps called synapses. These gaps are chemical synapses or electrical synapses which pass the signal from one neuron to the next.
