Document Summary
Each muscle fiber (striated) is individually innervated. Only contract: no such thing as inhibitory nerve fibers innervating striated muscle. Motor fibers: motor, nerve axon that innervate the striated muscle, if activated, will depolarize and bring about an action and that se/group of muscle. Motor neurons that innervate the striated muscles are called motor fibers. 4 proteins that make up the bulk of striated muscle: myosin, the thick myo filament. Myo filament- is a term to describe those protein structures: actin, the thin myo filaments. Myo filament- is a term to describe those protein structures. Studded along the this there will be two smaller proteins (below) [the tt complex] Myofilament is usually just the actin and myosin: troponin, tropomyosin. The two t proteins called the tt complex. If these would to be removed, there would be a myosin binding site: studded/ found along the actin myo filament. To mask/ cover the myosin binding site on the actin myo filament.
