Which of the following is not a function required for the coordination of movement?

Motor control is indeed a fundamental aspect of coordinating movement, encompassing the processes that enable the brain to plan, initiate, and regulate movement. This includes the integration of sensory input with motor output for the execution of smooth, precise movements.

When examining the other options, motor unit recruitment refers to the way muscles are activated to produce force and perform tasks, playing a critical role in coordinating and strengthening movements. Proprioception involves the body's ability to sense its position and movement in space, providing essential feedback that allows for the adjustment of motor actions. Balance is vital for maintaining stability and control during movement, influencing how the body responds to shifts in weight and posture.

In this context, every other option aligns directly with the coordination of movement. Therefore, motor control is integral, while the coordination of movement relies heavily on motor unit recruitment, proprioception, and balance, making it essential to recognize those components that directly contribute to effective movement coordination.
