Resting myofiber
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. Muscles are composed of long bundles of Myocytes (Muscle fibers). Myocytes contain thousands of myofibrils. Weba chain of small units of globular actin make up. F actin. during muscle contraction, each ______ monomer has an open active site to bind with the protein myosin. G actin. G actin is …
