The central nervous system is composed of the brain in the skull and the spinal cord in the vertebral column.
The spinal cord consists of the nerves that connect the CNS with the body’s muscles, glands, and sense organs.
The basic unit of the nervous system is the individual nerve cell or neuron.
In most neurons, generation of an electrical signal causes the release of neurotransmitters, which communicate with other cells.
Action potential propagation rapidly occurs in the axons of neurons covered by myelin.
In the brain, the oligodendrocytes form myelin sheath around multiple axons.
In the PNS, cells called Schwann cells form individual myelin sheath at regular intervals along the axons.
The spaces between adjacent sections of myelin where the axon’s plasma membrane is exposed to the extracellular fluid are the nodes of Ranvier.
