MUSCLE PHYSIOLOGY

Detailed explanation-1: -Fascia, connective tissue outside the epimysium, surrounds and separates the muscles. Portions of the epimysium project inward to divide the muscle into compartments.

Detailed explanation-2: -Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.

Detailed explanation-3: -The epimysium blends with the connective tissue of tendon if the muscle is inserted onto bone via tendon, but if inserted directly onto bone then the epimysium blends with the periosteum of the bone (Fig. 6.4).
