The cingulum is described from various brain images as a C-shaped structure within the brain that wraps around the frontal lobe to the temporal lobe right above the corpus callosum. It is located beneath the cingulate gyrus within the medial surface of the brain therefore encircling the entire brain.
Cingulum means "belt" in Latin. [25] The name was likely chosen because this cortex, in great part, surrounds the corpus callosum. The cingulate cortex is a part of the "grand lobe limbique" of Broca (1878) that consisted of a superior cingulate part (supracallosal) and an inferior hippocampic part (infracallosal). [26]
The cingulum is highlighted near the base. In dentistry , cingulum ( Latin : girdle or belt ) refers to an anatomical feature of the teeth . It refers to the portion of the teeth that forms a convex protuberance at the cervical third of the anatomic crown.
Cingulum, from the Latin for belt or girdle, may refer to: Cingulum (brain), white matter fibers found in the brain; Cingulum (tooth), a shelf at the margin of a tooth; A type of groove encircling the theca of dinoflagellates; Cingulum (Catholicism), a rope belt used by monastic order such as the Order of Saint John (Bailiwick of Brandenburg)
The cingulum forms from this lingual lobe of development. [12] The majority of a lingual surface's cervical third is made up of the cingulum. [13] On lower incisors, a cingulum usually is poorly developed or absent. Maxillary canines have a large, well-developed cingulum, [13] whereas the cingulum of mandibular canines is smoother and rounded. [14]

The lingual incisal edge is also raised slightly to the level of the marginal ridges. The lingual fossa is bordered incisally by the lingual incisal edge, mesially by the mesial marginal ridge, distally by the distal marginal ridge, and cervically by the cingulum. [13] Developmental grooves are found on the cingulum and lying into the lingual ...
The distal and mesial marginal ridges are evident and the cingulum is prominent. [13] The lingual fossa is more concave than the central incisor. [13] The cingulum will often have a deep developmental groove on the distal side that can continue well into the root. [13] The lingual view of the lateral incisor fits into the geometric shape of a ...
