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, 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)
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.
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]
Lingually, the surface of the tooth is much smoother compared to the very pronounced surface of the maxillary canine, and the cingulum is noted as less developed. The cusp may be lost with attrition over time and may resemble an upper second permanent incisor.
This is a list of Latin words with derivatives in English (and other modern languages). Ancient orthography did not distinguish between i and j or between u and v. [1] Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words.
The equivalent structure on upper molars is called the cingulum. The presence or absence of a cingulid is often a diagnostic feature for mammal remains. Some animals don't have a cingulid. Those that do may have them on only some, or all of the teeth, though most often on the molar teeth. It can be on the upper or lower teeth, or both.
