The central sulcus separates which lobes?

The central sulcus separates which lobes?

• A. Frontal and parietal lobes
• B. Occipital and temporal lobes
• C. Frontal and temporal lobes
• D. Parietal and occipital lobes

Answer: (A)

The central sulcus marks the boundary between the frontal and parietal lobes. It runs roughly from the top of the brain down toward the lateral sulcus, and it separates the precentral gyrus (the primary motor cortex) in the frontal lobe from the postcentral gyrus (the primary somatosensory cortex) in the parietal lobe. This division reflects a shift from motor planning and execution in the frontal area to sensory processing in the parietal area. Other boundaries are defined by different grooves: the border between occipital and parietal involves the parietooccipital region, and the frontal–temporal border runs along the lateral (Sylvian) fissure. So, the central sulcus separates the frontal and parietal lobes.
