Quizplus · Accepted Answer

The epineurium is the tough, fibrous sheath that forms the outermost layer of a peripheral nerve, providing protection to the nerve. The endoneurium is a delicate layer of connective tissue that surrounds individual axons within a nerve. The perineurium is a thicker layer of connective tissue that surrounds a group of axons called a fascicle. The neurilemma is a thin layer of Schwann cells that surrounds axons in the peripheral nervous system, aiding in axon regeneration. A fascicle is a bundle of axons within a nerve.
