Perimysium is a connective tissue sheath that surrounds bundles of muscle fibers, known as fascicles, within skeletal muscle. It is part of the three layers of connective tissue that make up muscle tissue, the others being the epimysium (which envelops the entire muscle) and the endomysium (which surrounds individual muscle fibers).
