Which region provides cognitive control for goal-directed movement?

• A. Prefrontal cortex
• B. Premotor cortex
• C. Primary motor cortex
• D. Parietal lobe

Answer: (A)

This question hinges on cognitive control of goal-directed movement—the ability to plan, maintain a goal, choose among options, and supervise motor output before any action is executed. The prefrontal cortex handles these executive functions, like working memory to keep the goal in mind, planning sequences of steps, evaluating outcomes, and inhibiting distractions or inappropriate responses. It’s what allows you to decide to pick up a cup, hold that intention, and adjust your plan if something unexpected gets in the way. The premotor cortex is more about organizing and preparing movements once a goal is already set, translating the plan into a motor sequence. The primary motor cortex executes the final commands to muscles. The parietal lobe integrates sensory information to help guide movement but doesn’t provide the top-down decision-making and planning that you need for goal-directed actions. So, the prefrontal cortex is the region that supplies that cognitive control for goal-directed movement.
