Question

the lateral and central fissure divide the brain into what?

○ 2 hemispheres
○ 4 lobes
○ 2 frontal planes
○ 3 hemispheres

Explanation:

The lateral (Sylvian) fissure and central (Rolandic) fissure help divide the cerebral cortex (part of the brain) into 4 lobes: frontal, parietal, temporal, and occipital. The longitudinal fissure divides the brain into 2 hemispheres, so "2 hemispheres" is incorrect. "2 frontal planes" is not a correct anatomical division here, and "3 hemispheres" is anatomically inaccurate.

Answer:

B. 4 lobes
