The main difference between these is that skeletal and cardiac muscles have a myofibril that is composed of actin and myosin. Cardiac muscle is striated like skeletal muscle as the actin and myosin are arranged in sarcomeres just as in skeletal muscle. Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs.
_____ muscle is the primary muscle of internal organs.
These are long and cylindrical with blunt ends. Cardiac muscle is striated but the bundles are connected at branching irregular angles called intercalated discs. Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. Cardiac Muscle Cardiac muscles are also involuntary in their action and are myogenic.
