Skeletal Muscle Concept Overview Physiology Interacti Vrogue Co Skeletal muscle cells contain an orderly array of contractile proteins and regulatory proteins. 5.) contractile proteins myosin and actin interact to cause contraction of the cell. 6.) regulatory proteins troponin and tropomyosin together act like a switch to determine when myosin and actin can interact. 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. Complete the skeletal muscle physiology assignment. muscles have the ability to contract, or shorten in length, to produce movement. the basic functional unit of a skeletal muscle fiber is the sarcomere. sarcomeres are connected in series within a myofibril and many myofibrils are contained within each muscle fiber (see figure 1). Skeletal muscle is one of the three types of muscle tissue, alongside cardiac and smooth muscle. it is classified as a striated muscle tissue, which functions to contract and permit movements under voluntary control. this article will discuss the structure of skeletal muscle tissue, it’s mode of contraction and relevant clinical conditions.
