Peripheral Nerve

Bundles of myelinated and unmyelinated axons organized by connective tissue layers. Schwann cells provide myelin for saltatory conduction; Remak bundles group unmyelinated C fibers. Regeneration after injury depends on Schwann cell scaffolding and axon regrowth rate (~1 mm/day).

Also known as: peripheral nerve trunk, nerve fascicle, somatic nerve
