WebWithin the nerve, axons are further bundled into fascicles, which are each surrounded by their own layer of fibrous connective tissue called perineurium. Finally, individual axons are surrounded by loose connective tissue called the endoneurium ( [link] ). These three layers are similar to the connective tissue sheaths for muscles. WebThe perineurium extends peripherally from the meninges to terminate at motor endplates of skeletal muscle fibers; it also merges with capsular sheaths of peripheral sensory …
