evidence: A nerve is an enclosed , cable-like bundle of axons -LRB- nerve fibers , the long and slender projections of neurons -RRB- in the peripheral nervous system .. peripheral nervous system. peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs .. electrochemical. electrochemical. In the central nervous system , the analogous structures are known as tracts .. central nervous system. central nervous system. tracts. Nerve tract. Neurons are sometimes called nerve cells , though this term is potentially misleading since many neurons do not form nerves , and nerves also include non-neuronal Schwann cells that coat the axons in myelin .. Schwann cells. Schwann cells. myelin. myelin. Each nerve is a cordlike structure containing bundles of axons .. Within a nerve , each axon is surrounded by a layer of connective tissue called the endoneurium .. axon. axon. endoneurium. endoneurium. The axons are bundled together into groups called fascicles , and each fascicle is wrapped in a layer of connective tissue called the perineurium .. fascicles. Nerve fascicle. perineurium. perineurium. Finally , the entire nerve is wrapped in a layer of connective tissue called the epineurium .. epineurium. epineurium
