heart muscles are distinct from skeletal muscles because the muscle fibers are laterally connected to each other. furthermore, just as with smooth muscles, their movement is involuntary. heart muscles are controlled by the sinus node influenced by the autonomic nervous system.

smooth muscles are controlled directly by the autonomic nervous system and are involuntary, meaning that they are incapable of being moved by conscious thought. functions such as heartbeat and lungs (which are capable of being willingly controlled, be it to a limited extent) are involuntary muscles but are not smooth muscles.

muscular system
there are three types of muscles—cardiac, skeletal, and smooth. smooth muscles are used to control the flow of substances within the lumens of hollow organs, and are not consciously controlled. skeletal and cardiac muscles have striations that are visible under a microscope due to the components within their cells. only skeletal and smooth muscles are part of the musculoskeletal system and only the skeletal muscles can move the body. cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. skeletal muscles are attached to bones and arranged in opposing groups around joints. muscles are innervated, to communicate nervous energy to, by nerves, which conduct electrical currents from the central nervous system and cause the muscles to contract.
