MUSCLE PHYSIOLOGY

Detailed explanation-1: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium .

Detailed explanation-2: -The epimysium is the dense connective tissue that surrounds the entire muscle tissue. The epimysium usually contains many bundles (fascicles) of muscle fibers. 2. The perimysium is the connective tissue that surrounds each bundle of muscle fibers.

Detailed explanation-3: -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.
