The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction. The two filaments are a thick one composed mostly of myosin, and a thin one composed mostly of actin. What do thick filaments in muscle fibers form?
WebMyofilaments — comprised of thick and thin filaments. The thick are comprised of myosin and the thin are comprised of actin, troponin, and tropomyosin. Sarcomere — the basic contractile unit of the muscle. Has Z-lines on either end along with A-band and two 1/2 I-bands. Z-disk ultrastructure — comprised of Z filaments. WebMyofibrils are the thin fibres made up of acti9n and myosin filaments and are present among the cytoplasm of skeletal muscle fibres. They are the contractile units that are responsible for the contraction of skeletal muscles. Each skeletal muscle fibre is innervated by a separate axon and can undergo contraction independent of other cells.
