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: -Approximately 20–80 of these muscle fibers are grouped together in a parallel arrangement called a muscle fascicle or fiber bundle that is encapsulated by a perimysium, which is thicker than the epimysium enclosing each of the bundled muscle fibers.
Detailed explanation-3: -Muscle fibres are arranged into individual bundles, each called a fascicle, within each skeletal muscle, by a middle layer of connective tissue called the perimysium.
