Abstract
The macroscopic anatomy of peripheral nerves results from the hierarchic arrangement of nerve fibers formed by microscopic groups of motor and sensory neuronal cytoplasmic elongations known as axons. The latter enable conduction of electrical impulses along their plasma membranes, as well as chemically mediated signal transduction throughout cytoplasmic organelles. Most peripheral nerves are mixed nerves containing efferent motor fibers, afferent sensory fibers, and sympathetic fibers. The initial segment of an axon (AIS) originates in the soma and is located between the cell body and the beginning of the myelin sheath
