MICROANATOMY

Detailed explanation-1: -The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium.

Detailed explanation-2: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium.

Detailed explanation-3: -The fiber surface is covered by the plasma membrane (sarcolemma) and external lamina.

Detailed explanation-4: -Skeletal muscles are grouped into fascicles, which are bunches of muscle fibers surrounded by a perimysium.

Detailed explanation-5: -Perimysium is a sheath of connective tissue that groups muscle fibers into bundles (anywhere between 10 and 100 or more) or fascicles. Structure of a skeletal muscle. (Perimysium labeled at top center.) Studies of muscle physiology suggest that the perimysium plays a role in transmitting lateral contractile movements.
