Explanation:

• Myelin sheath: Insulates nerve fibers, formed by Schwann cells (PNS) or oligodendrocytes (CNS), surrounds individual nerve fibers.
• Perineurium: Connective tissue layer that surrounds bundles (fascicles) of nerve fibers.
• Epineurium: Outermost connective tissue layer that surrounds the entire nerve (containing multiple fascicles), enclosing nerve fibers.
• Motor endplate: Specialized region of a muscle fiber membrane at the neuromuscular junction, not a tissue surrounding nerve fibers.

Answer:

A. myelin sheath, B. perineurium, C. epineurium
