Epimysium

Epimysium is a layer of connective tissue, which ensheaths the entire muscle. It is composed of dense irregular connective tissue. It is continuous with fascia and other connective tissue wrappings of muscle including the endomysium, and perimysium. It is also continuous with tendons where it becomes thicker and collagenous. The epimysium also protects muscles from friction against other muscles and bones
