Which term is the connective tissue that surrounds the entire muscle?

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

Answer: (A)

The main idea is how skeletal muscle is organized by connective tissue layers. The outermost sheath that surrounds the entire muscle is the epimysium. It forms a tough, protective covering around the whole muscle belly and often blends with the deep fascia and with the tendons at the ends, helping to transmit force generated by the muscle. Inside, the endomysium wraps each individual muscle fiber, and the perimysium groups fibers into fascicles. Fascia is a broader connective tissue layer that can envelop muscles or muscle groups and adjacent structures, but it is not the specific sheath around a single muscle.
