WebPeripheral nerves contain fascicles of nerve fibers consisting of axons. In peripheral nerve fibers, axons are ensheathed by Schwann cells, which may or may not form myelin around … WebScope Note. The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

WebPeripheral nerve. One Schwann cell forms a segment, called an internode, of a myelin sheath around a portion of an axon. The myelin sheath is formed by continuous, multiple wrappings of a Schwann cell plasma membrane, producing a lipid-rich insulation that increases conduction speed of nerve impulses. The space between adjacent internodes is …
