Which connective tissue surrounds a fascicle in skeletal muscle?

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

Answer: (C)

The connective tissue layer that surrounds a fascicle is the perimysium. A fascicle is a bundle of muscle fibers, and the perimysium wraps around that bundle to hold it together and to house the larger blood vessels and nerves that supply the fibers inside. This organization allows efficient delivery of oxygen and nutrients and coordination of force within the muscle. The endomysium surrounds each individual muscle fiber, not the bundle. The epimysium encases the entire muscle, and fascia refers to broader sheets that organize groups of muscles or large regions.
