peripheral neurons
Wednesday 20 February 2008
Peripheral neurons consist of a cell body and a long process, or axon, which may lead one meter in length.
Short segments of the axon are wrapped with an insulating myelin sheath formed by Schwann cells.
Axons are grouped together into fascicles, several of which are enclosed in the epineurium (a sheath of connective tissue) to form a peripheral nerve.
The major types of peripheral neurons are sensory or afferent neurons, which are responsible from stimulus reception, and motor or efferent neurons, which control organs and tissues such as glands and muscles.
