Epimysium of muscle

The individual muscle cells are encased in collagenous tissue that can be subdivided into the portion that is intimate contact with the cell called the basement membrane and a more distal portion called endomysium.

A group of fascicle of muscle cells is surrounded by a more robust collagenous connective tissue network called the perimysium.

An anatomical muscle consists of group of fascicles and is surrounded by the epimysium. It is a thick layer of connective tissue around the entire muscle. It is through the epimysium that the main product of muscle (shortening) is coupled to bone via the myotendinous junction.

The epimysium is generally easily separated from the body of the muscle, whereas perimysium and endomysium are not practically separated from meat.

The epimysium is generally continuous with the tendons. In some cases, the epimysium may appear to extend into the body of the muscle.
