describe the difference between smooth,skeletal and cardiac muscle
In skeletal muscle, the contraction allows the bone to move, thereby allowing your body to move. In the heart, the cardiac muscle pumps the blood into the arteries. The smooth muscles in blood vessels are used to pump blood in one direction (in veins, which is in low pressure, there are valves which prevents backflow).
Cardiac muscles and skeletal muscles are also different in their shape. While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles. The skeletal muscles are attached to the bone through tendons. The skeletal muscles also contain myoblasts, which form the fibers in the muscles. The cardiac muscles are seen in the myocardium of the heart. The cardiac muscles contain intercalated discs and T-tubules, which connects the myocyte to the synctium. The skeletal muscles are tightly bound together when compared to cardiac muscles.
