Endomysium : a delicate connective tissue sheath surrounds muscle fibre. Endomysium : a delicate connective tissue sheath surrounds muscle fibre. Perimysium : a coarser fibrous membrane surrounds several sheathed muscle fibers to form bundle of fibers called a fascicle. Perimysium : a coarser fibrous membrane surrounds several sheathed muscle fibers to form bundle of fibers called a fascicle. Epimysium : a tougher overcoat of connective tissue surrounds many fascicles. Epimysium : a tougher overcoat of connective tissue surrounds many fascicles.
