Verified step by step guidance

Step 1: Understand the structure of skeletal muscle. Skeletal muscle is organized into layers of connective tissue sheaths that provide support and protection. These layers include the epimysium, perimysium, and endomysium.

Step 2: Define each connective tissue sheath. The epimysium surrounds the entire muscle, the perimysium surrounds bundles of muscle fibers called fascicles, and the endomysium surrounds individual muscle fibers.

Step 3: Clarify the role of the sarcolemma. The sarcolemma is not a connective tissue sheath; it is the plasma membrane of a muscle fiber, located beneath the endomysium.

Step 4: Identify the correct connective tissue sheath for individual muscle fibers. Based on the definitions, the endomysium is the connective tissue sheath that directly surrounds each individual muscle fiber.

Step 5: Review the hierarchy of muscle organization to reinforce understanding. Muscle fibers are surrounded by the endomysium, grouped into fascicles surrounded by the perimysium, and the entire muscle is encased in the epimysium.
