MICROANATOMY

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 muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.

Detailed explanation-3: -Skeletal Muscles Myofibers are grouped into larger units called muscle fascicles, which are enveloped together by connective tissue (called epimysium) into anatomically recognized muscles. Epimysium extends internally between fascicles, forming septa that are called perimysium.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
