Postcentral sulcus
Sulcus postcentralis
Definition
The postcentral sulcus is a significant sulcus found in the parietal lobe. It runs alongside the central sulcus, positioned behind it, and stretches downward and forward from the upper edge of the cerebral hemisphere. Along with the central sulcus, it creates boundaries of the postcentral gyrus, which is also known as the primary sensory area. The postcentral sulcus also reaches the medial side of the cerebral hemisphere, where it connects with the marginal sulcus branch of cingulate sulcus, forming the back edge of the paracentral lobule.
