NEET PG DENTAL EXAM

Detailed explanation-1: -The central sulcus runs posterior-medial to anterior-lateral and separates the frontal lobe from the parietal lobe. The parieto-occipital sulcus separates the parietal lobe from the occipital lobe.

Detailed explanation-2: -The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.

Detailed explanation-3: -The central sulcus, or fissure of Rolando, separates the frontal and parietal lobes, and the deeper lateral sulcus, or fissure of Sylvius, forms the boundary between the temporal lobe and the frontal and parietal lobes.

Detailed explanation-4: -The central sulcus is the next posterior sulcus. L sign: the superior frontal gyrus intersects precentral gyrus in an “L” junction. The central sulcus is immediately posterior. lower T sign: the inferior frontal sulcus terminates posteriorly in the precentral sulcus in a “T” junction.
