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: -Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.

Detailed explanation-3: -The endomysium surrounding muscle fibers is connected to the perimysium by intermittent perimysial junctional plates (PJPs), described by Passerieux et al.

Detailed explanation-4: -The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue.

Detailed explanation-5: -The endomysium is the connective tissue that surrounds each muscle fiber (cell). The perimysium encircles a group of muscle fibers, forming a fascicle. The epimysium encircles all the fascicles to form a complete muscle.
