The orientation, placement, and coordination of these muscles allow the human body to produce a wide range of voluntary movements. The muscular system consists of skeletal muscles and their associated connective tissues. It does not include cardiac muscle and smooth muscle, which are associated with the systems in which they are found, such as the cardiovascular, digestive, urinary, or other organ systems.
