WebWhat are nerve fibers? 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. ... Each peripheral nerve consists of parallel bundles of nerve fibers, called nerve fascicles. WebThese neurons are pseudounipolar and contain an axon-like process that bifurcates with one branch extending toward the periphery and the other branch heading toward the grey matter of the spinal cord. Fibers heading toward the periphery leave the ganglion through the spinal nerve, where they run together with motor fibers.
