GROSS ANATOMY

Detailed explanation-1: -The lateral fissure (Sylvian fissure) is a laterally located horizontal fissure and separates the temporal lobe from the frontal and parietal lobe. The parietal lobe is posterior to the central sulcus and anterior to the parieto-occipital sulcus. This lobe controls perception and sensation.

Detailed explanation-2: -The frontal lobe is separated from the parietal lobe by a space called the central sulcus, and from the temporal lobe by the lateral sulcus. The frontal lobe is generally where higher executive functions including emotional regulation, planning, reasoning and problem solving occur.

Detailed explanation-3: -Ventral Precentral Region The central sulcus (the sulcus of Rolando) forms the boundary between the frontal and the parietal lobes on the lateral and medial surfaces of the cerebral hemispheres (Figs. 10 and 11).

Detailed explanation-4: -Examination of the lateral surface of the brain will reveal the lateral sulcus (the Sylvian fissure). This groove separates the temporal lobe from the parietal lobe.

Detailed explanation-5: -The major motor and sensory areas are separated by the central sulcus and the immediate areas anterior (precentral gyrus) and posterior (postcentral gyrus), forming, respectively, the primary motor and sensory cortices.
