Central sulcus

Also known as lateral sulcus or fissure (from Latin sulcus lateralis), lateral sulcus of the brain, lateral cerebral sulcus, Sylvian fissure, Sylvian fissure, Sylvian fossa, Sylvian fossa, Sylvian fissure, Sylvian fissure, sulcus lateralis cerebri.

This deep fold that begins in the anterior perforated substance. It extends laterally (outward) between the temporal lobe and frontal lobe, and turns backward between the temporal lobe and parietal lobe. It divides into three branches: posterior, ascending and anterior.

In its inferior part the Sylvian fissure separates the frontal lobe and the temporal lobe and in its superior part the parietal lobe from the temporal lobe. It is present in both cerebral hemispheres but is longer in the left hemisphere.

The lateral sulcus has several lateral branches. Two of the most prominent and most regularly encountered are the ascending (also called vertical) branch and the horizontal branch, which subdivides the inferior frontal gyrus. The sulcus Sylvius also contains the transverse temporal gyrus, which is part of the auditory cortex.

Corpus callosum

Anatomically, the brain is first divided into two hemispheres, then into lobes and finally these are composed of grooves or fissures that create another type of separation. Therefore, it is a complex organ that requires different structures.

Besides creating a division between the frontal lobe and the parietal lobe, as it constitutes a cut in the cerebral anatomy, it is composed of a portion of the motor cortex and another portion of the somatosensory cortex. In other words, the central sulcus is involved in the functions of the human body including movements and sensations.

Sylvian fissure separating

The Sylvian fissure is a lateral cut that is located below the Rolando’s sulcus, specifically at the sides of the brain. So both are responsible for creating thin spaces between the cerebral lobes.

The brain, besides being divided into two hemispheres and 4 lobes, also comprises in its anatomy several sulci. These are in charge of separating each lobe and the cortexes.

It is responsible for creating a division of the brain into two parts, i.e. one superior and one inferior, thus providing a cut between the temporal lobe that is located below and the frontal and parietal lobes that are above the cerebral sulcus.

The main function of the sulci is to create a differential cut between the lobes of the brain, and in this case the lateral cut divides the frontal and parietal lobes from the temporal lobe below them. So it is also part of the auditory cortex, the insula can be located in the internal area of the cut and it is also one of the grooves through which the middle cerebral artery passes.
