 | | 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. |
 | | Commonly, the epimysium, perimysium, and endomysium extend beyond the fleshy part of the muscle, the belly or gaster, to form a thick ropelike tendon or a broad, flat sheet-like aponeurosis. |
