i dont know yet

Explanation:

• Dura mater: It is a tough membrane that covers the brain and spinal cord, not a covering of peripheral nerves.
• Perineurium: The perineurium is the middle (central) layer of connective - tissue covering of a peripheral nerve. It is composed of collagenous fibers, elastic fibers, and fibrocytes and divides the nerve into fascicles.
• Endoneurium: It is the innermost layer that surrounds individual nerve fibers.
• Epineurium: It is the outermost layer that surrounds the whole nerve.

Answer:

Perineurium
