Etymology: "Epimysia" is the plural of "epimysium," the sheath of connective tissue that wraps an entire muscle. The term is a modern anatomical coinage built from Greek: "epi-" meaning "upon" and "mys," meaning "muscle" or "mouse," the same root that gave Latin "musculus," or "little mouse," the source of English "muscle." The Latinized "-ium" ending marks it as a technical term, and its neuter plural takes "-ia."
