Bundles of myofilaments
WebJan 5, 2024 · Myofilaments are the protein fibers that make up the contractile elements of skeletal muscle cells. They are composed of two different proteins, actin and myosin, and are responsible for muscle … WebMyocytes, sometimes called muscle fibers, form the bulk of muscle tissue. They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue.
Bundles of myofilaments
Did you know?
Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, a thin one of mostly actin, and a very thin one of mostly titin.
