Question: 1 / 445

What encloses the contents of a muscle fiber?

Perimysium

Fascicle

Epimysium

Sarcolemma

The correct answer is D. The sarcolemma is the correct answer because it is the plasma membrane that surrounds each individual muscle fiber. The perimysium refers to the connective tissue that surrounds each bundle of muscle fibers, known as the fascicle. The epimysium refers to the connective tissue that wraps around the entire muscle. The fascicle, on the other hand, is a small bundle of muscle fibers within a muscle. Therefore, the sarcolemma is the only option that specifically encloses the contents of a single muscle fiber.
