anatomical entity anatomical entity Mus <genus> anatomical space sulcus of brain Indentation on the surface of the brain or spinal cord that forms a recognizable landmark, e.g., central sulcus, sulcus limitans (CUMBO) uberon cerebral sulci A depression or fissure in the surface of the brain. It surrounds the gyri, creating the characteristic appearance of the brain in humans and other large mammals. sulci are considered absent from lissencephalic mammals such as mice, but they may possess fissures. For example, the Allen mouse brain Atlas includes hippocampal, rhinal and choroid fissure. For this reason we do not place a taxon constraint on this class fissure of brain HBA:9352 cerebral sulci sulcus DHBA:10610 NCIT:C32292 UBERON:0013118 cerebral sulcus sulci & spaces
