How do mscle pairs work together to move a limb?

Muscle pairs work together to move a limb through a process called antagonistic contraction. When one muscle in the pair, known as the agonist, contracts to produce movement, its counterpart, the antagonist, relaxes to allow the movement to occur smoothly. For example, when bending the elbow, the biceps (agonist) contracts while the triceps (antagonist) relaxes. This coordinated action enables precise and controlled movement of the limb.
