Which lobe is associated with planning of motor activities?

• A. Frontal
• B. Parietal
• C. Temporal
• D. Occipital

Answer: (A)

Motor planning for movements is handled by the frontal lobe, especially the premotor cortex and supplementary motor area. These regions organize and sequence actions before they are carried out, with the actual execution carried out by the primary motor cortex within the same lobe. Think of it as planning and programming the steps of a movement, then the primary motor cortex activates the muscles to perform it. The parietal lobe handles sensory information and spatial aspects of movement, the temporal lobe deals with memory and hearing, and the occipital lobe processes vision. Damage to the frontal motor planning areas can lead to apraxia, highlighting their role in planning movements.
