where is striated muscle found in the human body
Striated muscle tissue
Contractions in striated muscles are voluntary , except for the heart muscle , in which contractions are regulated involuntarily by the sinoatrial node . Cardiac muscle is often treated separately from the other striated muscles , as it has somewhat different characteristics . During voluntary contractions , a striated muscle is extended by the action of an antagonistic muscle . All striated muscles are attached to some component of the skeleton , unlike smooth muscle , which composes hollow organs such as the intestines or blood vessels . The fibers of striated muscle have a cylindrical shape with blunt ends , whereas those in smooth muscle can be described as being spindle - like with tapered ends . Two other characteristics that differentiate striated muscle from smooth muscle are the facts that the former has more mitochondria and contains cells that are multinucleated .
