Gingival sulcus at neck of mammalian tooth Pollen grains of Cercis are sulcate, with reticulate surface. Rotating image of human brain, illustrating the lateral sulcus in the brain. In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae).
The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral ...
Operculated sulcus separates by its lips into two areas and contains a third area in the walls of the sulcus e.g. lunate sulcus is an operculated sulcus, separating the striate and parastriate areas. On the basis of depth: Complete sulcus is very deep so as to cause elevation in the walls of the lateral ventricle.
The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).

Brodmann area 52 is found along the lateral sulcus, which is a groove on the side of the brain, on the upper part of the temporal lobe. The area is located near the boundary between the temporal lobe and the insula , another important brain region involved in sensory processing and emotional responses .
Although the supramarginal gyrus is not considered a major portion of the language circuit, it still works with the angular gyrus to attempt to link words with meanings. It is also bound caudally by the lateral sulcus, one of the most prominent structures found in the brain. [citation needed]
