The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.

What are the parts and functions of the muscular system?
The muscles within the muscular system contribute to proper organ function, help circulate blood, and allow for movement. The major components of this system include cardiac muscle, smooth muscle and skeletal muscle.
What functions does the muscular system perform?
The muscular system consists of various types of muscle that each play a crucial role in the function of the body. Muscles allow a person to move, speak, and chew. They control heartbeat, breathing, and digestion.
