The parietal lobe (Lobus parietalis) is one of the cerebral lobes. It lies directly posterior to the Frontal lobe and is bounded by the Sulcus centralis, Sulcus parietooccipitalis, and Sulcus lateralis.
Anatomy
The parietal lobe begins with the Postcentral gyrus posterior to the sulcus centralis. Ventrally, the parietal lobe is bounded by the sulcus lateralis. Posteriorly, the parietal lobe is separated from the Occipital lobe by the sulcus parietooccipitalis.
Posterior to the postcentral gyrus is the sulcus postcentralis, which separates the postcentral gyrus from the Inferior parietal lobule and Superior parietal lobule. These two lobules are separated from each other by the Intraparietal sulcus. At the end of the sulcus lateralis is the Supramarginal gyrus, and ventral to it is the Angular gyrus; together, these form the Precuneus on the medial surface.
