Epimysium, perimysium, and endomysium are the three layers of connective tissue that extend from the fascia and protect the muscle fibers. Epimysium is the outer most layer of connective tissue of individual muscle fiber. It encircles the entire muscle. Epimysium consists of dense irregular connective tissue. It serves to separate the muscle fibers from the other types of tissues present in the area to facilitate their independent movement.
