Frog Heart Muscle Tissue

In order to carry out their daily activities, frogs depend upon three types of muscle; striated (skeletal), cardiac (heart), and smooth. Striated muscles are composed of elongated fibers and are used for actions such as hopping. As indicated by the name, the tissue exhibits striped or striated patterns when examined under a microscope. Smooth muscle cells, on the other hand, are usually smaller than striated ones and have a distinctly different appearance. Allied with autonomic or involuntary systems, smooth muscle tissues can be found in the digestive system, the blood vessels, and a large number of the internal organs. Cardiac muscle, however, is a highly specialized component of the heart, which appears similar to striated muscle, but functions involuntarily in a manner comparable to smooth muscle.
