MUSCLE PHYSIOLOGY

Detailed explanation-1: -The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.

Detailed explanation-2: -Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium.

Detailed explanation-3: -Each muscle fiber (cell) is covered by endomysium and the entire muscle is covered by epimysium. When a group of muscle fibers is “bundled” as a unit within the whole muscle it is called a fascicle. Fascicles are covered by a layer of connective tissue called perimysium (see Figure 10.2.

Detailed explanation-4: -They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue.
