WebJul 26, 2024 · The arrangement of a T-tubule with the terminal cisternae of the SR on either side is called a triad (Figure 9.3.3). The triad surrounds the cylindrical structure of the myofibril. Figure 9.3.3: The Triad. Narrow T-tubules permit the conduction of electrical impulses. The SR functions to regulate intracellular levels of calcium. WebThe functional characteristics of a skeletal muscle cell : The cell membrane is called the sarcolemma. This membrane is structured to receive and conduct stimuli. The sarcoplasm of the cell is filled with contractile myofibrils and this results in the nuclei and other organelles being relegated to the edge of the cell.

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, tri…
WebA triad consists of two terminal cisterns with a T-tubule in the middle. not well developed, a true triad does not exist.
