The concept of the myofibril triad

WebOct 10, 2024 · Myofibrils are rod shaped subunits of muscle cells. The actin and myosin filaments making up the myofibrils are organized into sarcomeres. Under a microscope, sarcomeres give skeletal muscle a … WebThe triad surrounds the cylindrical structure called a myofibril, which contains actin and myosin. The T-tubules carry the action potential into the interior of the cell, which triggers the opening of calcium channels in the membrane of the adjacent SR, causing Ca ++ to diffuse out of the SR and into the sarcoplasm.
