WebDepending on their specific characteristics, muscles are divided into three categories – Skeletal muscle, Cardiac muscle and Smooth muscle. Skeletal muscles are attached to bones, cardiac muscles are found in the heart and smooth muscles are found in the stomach, gut walls, walls of the blood vessels, and various internal organs of the body. In the histology of skeletal muscle, a triad is the structure formed by a T tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side. Each skeletal muscle fiber has many thousands of triads, visible in muscle fibers that have been sectioned longitudinally. (This property holds because T tubules run perpendicular to the longitudinal axis of the muscle fiber.) In mammals, triads …

T-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells. With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration.
