"Unlike skeletal and cardiac muscle tissue, smooth muscle tissue is not striated since there are no sarcomeres present. Skeletal muscles are attached to some component of the skeleton, and smooth muscle is found in hollow structures such as the walls of intestines or blood vessels. The fibres of striated muscle have a cylindrical shape with blunt ends, whereas those in smooth muscle are spindle-like with tapered ends. Striated muscle tissue has more mitochondria than sm… " - Shape of striated muscle cell
