Which cortex is associated with planning movements before execution?

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

Answer: (A)

Planning movements before execution is a function of the premotor cortex. This area sits in the frontal lobe just in front of the primary motor cortex and helps prepare and organize motor programs, using sensory information to decide what action to take and how to sequence the muscles before any movement is actually carried out. The primary motor cortex then carries out those plans by sending the final commands to the muscles. The frontal lobe includes many higher-level functions, but planning specific movements is a hallmark of the premotor regions. The parietal lobe, in contrast, is mainly about processing sensory information and spatial relations, not directly about planning motor actions.
