Frogs depend on several types of muscles to carry out their normal daily activities such as pumping blood, breathing, moving about, and retrieving food. The three types of muscle are striated (skeletal), cardiac (heart), and smooth. Skeletal muscles, such as those that enable a frog to leap long distances, are comprised of narrow and wide elongated fibers. As the name implies, the tissue displays striped or striated patterns when observed under a microscope. Bundled together in cords, these muscles are connected to the bones by tendons. Striated tissue cells are among the largest cells in the body.
