WebThe longitudinal fissure separates the cerebral hemispheres from the cerebellum. Nearly the entire surface of the cerebral hemispheres is marked by shallow grooves called gyri. Nearly the entire surface of the cerebral hemispheres is marked by elevated ridges called sulci. The cerebral hemispheres account for about 83% of total brain mass.

In neuroanatomy, a sulcus (Latin: "furrow", pl. sulci) is a depression or groove in the cerebral cortex. It surrounds a gyrus (pl. gyri), creating the characteristic folded appearance of the brain in humans and other mammals. The larger sulci are usually called fissures. See more Sulci, the grooves, and gyri, the folds or ridges, make up the folded surface of the cerebral cortex. Larger or deeper sulci are termed fissures, and in many cases the two terms are interchangeable. The folded cortex creates a … See more Sulci are divided into following categories: On the basis of function: 1. A limiting sulcus separates at its floor into two areas … See more The variation in the number of fissures in the brain (gyrification) between species is related to the size of the animal and the size of the brain. … See more • Calcarine sulcus • Central sulcus • Central sulcus of insula • Cingulate sulcus See more • Sulcus (morphology) See more • Visual explanation of gyri, sulci, and fissures See more WebA depression or shallow groove on the surface of an organ, (pl. sulci) ...
