Word Origin and History for muscle Expand. n. late 14c., from Middle French muscle muscle, sinew (14c.) and directly from Latin musculus a muscle, literally little mouse, diminutive of mus mouse (see mouse (n.)). So called because the shape and movement of some muscles (notably biceps) were thought to resemble mice. The analogy was made in Greek, too, where mys is both mouse and muscle, and its comb. form gives the medical prefix myo-. In Middle English, lacerte, from the Latin word for lizard, also was used as a word for a muscle. Musclez & lacertez bene one selfe Ã¾ing, Bot Ã¾e muscle is said to Ã¾e fourme of mouse & lacert to Ã¾e fourme of a lizard.
Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis. Muscle fibres are cylindrical, and multinucleated.uscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber.
