ANATOMY

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: -A connective tissue band, called the epimysium, surrounds several fascicles. A perimysium surrounds an individual fascicle. An individual muscle fiber in a fascicle is invested in an endomysium.

Detailed explanation-3: -Muscle connective tissue is found at three levels of scale: the epimysium, which surrounds the muscle; the perimysium, which surrounds bundles of muscle fibers; and the endomysium, which surrounds muscle fibers.

Detailed explanation-4: -Perimysium is a continuous layer of collagenous connective tissue that separates the skeletal muscle tissue into muscle fascicles (i.e., bundles of muscle cells).
