WebJan 1, 2015 · The basic functional and also morphological unit of a peripheral nerve is an individual nerve fiber (neurofibra peripherica). A nerve fiber is a long process of nerve cell (neurone) called the axon. The nerve cell’s body is anatomically situated in the central nervous system or within the ganglia of the peripheral nervous system.

WebThere are four subdivisions of group A nerve fibers: alpha (α) Aα; beta (β) Aβ; , gamma (γ) Aγ, and delta (δ) Aδ. These subdivisions have different amounts of myelination and axon thickness and therefore transmit signals at different speeds. Larger diameter axons and more myelin insulation lead to faster signal propagation.
