Which connective tissue layer surrounds the entire skeletal muscle?

Which connective tissue layer surrounds the entire skeletal muscle?

• A. Endomysium
• B. Perimysium
• C. Epimysium
• D. Fascia

Answer: (C)

The outermost connective tissue layer that directly surrounds a whole skeletal muscle is the epimysium. Inside this muscle, fibers are grouped into fascicles, each fascicle wrapped by the perimysium, and each individual muscle fiber wrapped by the endomysium. Fascia is a broader connective tissue network that can surround muscles or muscle groups externally, but the specific layer encasing the entire muscle itself is the epimysium. The epimysium is dense irregular connective tissue that helps transmit the force of contraction to the tendon and contains the nerves and blood vessels servicing the muscle.
