| lobus occipitalis cerebri | The posterior, somewhat pyramid-shaped part of each cerebral hemisphere, demarcated by no distinct surface markings on the lateral convexity of the hemisphere from the parietal and temporal lobes, but sharply delineated from the parietal lobe by the parieto-occipital sulcus on the medial surface. Synonym: lobus occipitalis cerebri, occipital lobe. (05 Mar 2000) |
| lobus parietalis cerebri | The middle portion of each cerebral hemisphere, separated from the frontal lobe by the central sulcus, from the temporal lobe by the lateral sulcus in front and an imaginary line projected posteriorly, and from the occipital lobe only partially by the parieto-occipital sulcus on its medial aspect.
