multiple choice question. in the picture indicating functional areas of the cerebral cortex, arrow a is…

Answer:

The primary motor area is located in the pre - central gyrus, and the cutaneous sensory area (somatosensory area) is located in the post - central gyrus. Typically, the pre - central gyrus is more anterior and the post - central gyrus is more posterior. Based on the general location of functional areas in the cerebral cortex, if arrow A is pointing to an anterior area and arrow B is pointing to a more posterior area, arrow A is likely pointing to the primary motor area and arrow B is likely pointing to the cutaneous sensory area. So the answer is cutaneous sensory area; primary motor area.

Brief Explanations:

The primary motor area controls voluntary movements and is in the pre - central gyrus. The cutaneous sensory area processes sensory information from the skin and is in the post - central gyrus. Location in the cerebral cortex helps identify these areas.
