Explanation:
Heart muscles or cardiac muscles have alternate striations i.e. they give a striated appearance due to the presence of alternate thick and thin filaments of myosin and actin. These muscles are involuntary and are regulated by action potentials and calcium concentrations. The other options are the muscles that are either under autonomous control or under control of the will.
