A neuron is a nerve cell. These cells are specialized to transmit one-way messages. A nerve is a bundle of many neurons.
The dendrites conduct impulses toward the soma (cell body). A single neuron may have as many as hundreds of dendrites.
After being received through the dendrites, a nerve signal passed through the soma (cell body) where the nucleus is located. The nucleus contains the neuron's DNA.
The axon conducts impulses away from the soma (cell body). Neurons have only one axon arising from the cell body.
The myelin sheath is a whitish, fatty material covering the axon of a neuron. It functions to speed the nerve impulse transmission. In the peripheral nervous system (PNS) Schwann cells produce the myelin sheath around axons. In the central nervous system (CNS) Oligodendrocytes produce myeline sheaths around axons.
The axon ends in the axon terminal. Axon terminals contain vesicles with neurotransmitters, waiting to be released.
Axon terminals are separated from the next neuron by the synaptic cleft. The junction between nerves is known as the synapse.
