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]
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 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.
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 suffix -cingulum, literally 'belt', refers to a band of 12 triangles joining the two wedges. [1] The resulting polyhedron has 20 equilateral triangles and 4 squares, making 24 faces. [ 2 ] . All of the faces are regular , categorizing the disphenocingulum as a Johnson solid —a convex polyhedron in which all of its faces are regular ...
The marginal ridges and the cingulum of the tooth are well-developed. The cingulum reaches incisally a great length and is large enough to create small fossa on either side of it. Depicted by the cementoenamel junction , the cervical line is the border between the root and crown of a tooth.
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.
