Parietal lobe

The parietal lobe (Lobus parietalis) is one of the cerebral lobes of the cerebrum. It lies directly adjacent posteriorly to the frontal lobe and is bounded by the central sulcus, parietooccipital sulcus and lateral sulcus.

Anatomy

The parietal lobe begins with the postcentral gyrus behind the central sulcus. Ventrally, the parietal lobe is bounded by the lateral sulcus. Posteriorly, the parietal lobe is separated from the occipital lobe by the parietooccipital sulcus.

Posterior to the postcentral gyrus is the postcentral sulcus, which separates the postcentral gyrus from the inferior parietal lobule and superior parietal lobule. These two lobules are separated by the intraparietal sulcus. At the end of the lateral sulcus is the supramarginal gyrus and ventral to it the angular gyrus, which together form the precuneus on the medial surface.
