Myelinated nerve

Definition

noun

A nerve cell in which the axon is surrounded by a layer of Schwann cell membranes of myelin sheath.


Supplement

The myelin sheath that envelopes the nerve cell is crucial for faster conduction of action potential. This type of nerve cell is found in the peripheral nervous system (especially the sensory and motor neurons) and the white matter of central nervous system
