Verified step by step guidance
1
Begin by identifying the major lobes of the brain: frontal, parietal, occipital, and temporal. Each lobe is separated by specific grooves or sulci.
Understand that the central sulcus is a prominent groove on the surface of the brain. It plays a key role in separating the frontal lobe from the parietal lobe.
The central sulcus is located approximately halfway between the anterior and posterior parts of the brain, running vertically from the top of the brain down towards the lateral sulcus.
Differentiate the central sulcus from other grooves: the parieto-occipital sulcus separates the parietal lobe from the occipital lobe, the lateral sulcus separates the temporal lobe from the frontal and parietal lobes, and the longitudinal fissure divides the two cerebral hemispheres.
Conclude that the central sulcus is the correct groove that separates the frontal lobe from the parietal lobe, based on its anatomical position and function.
