what body system causes muscles to contract
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a personâs body weight.Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.elated to the function of movement is the muscular systemâs second function: the maintenance of posture and body position. Muscles often contract to hold the body still or in a particular position rather than to cause movement.
