We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin.Cardiac muscle is able to contract and relax, unlike skeletal muscles which only contract. This means that cardiac tissue will have far more irregular shapes than skeletal muscles. Cardiac muscle cells contain T tubules that connect to the sarcoplasmic reticulum which stores the calcium ions needed for the contraction of the cell.Muscles attach to bones directly or through tendons or aponeuroses. Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm.The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle). Explanation: The myofibrils inside muscle cells contain proteins that contract and expand the muscle.Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems (Figure \(\PageIndex{1}\).a,b).Figure 10.4 Muscle Fiber A skeletal muscle fiber is surrounded by a plasma membrane called the sarcolemma, which contains sarcoplasm, the cytoplasm of muscle cells.
