Anatomical terms of microanatomy [ edit on Wikidata ] A cementoblast is a biological cell that forms from the follicular cells around the root of a tooth , and whose biological function is cementogenesis , which is the formation of cementum (hard tissue that covers the tooth root).
Cementum situated around a human molar The cementum is the surface layer of the tooth root, covering the dentin (which is labeled B).Rather than being a passive entity like paint on a wall, cementum is a dynamic entity within the periodontium.
The sheath is also responsible for multiple or accessory roots (medial growth) and lateral or accessory canals in the root (break in epithelium). [3] It is controversial, but HERS may be involved in cementogenesis and the secreting of cementum, or that HERS-derived products might be related to enamel-related molecules, and that these proteins might initiate acellular cementum formation.
The other dominant hypothesis, the "clone model", proposes that the epithelium programs a group of ectomesenchymal cells to generate teeth of particular shapes. This group of cells, called a clone, coaxes the dental lamina into tooth development, causing a tooth bud to form. Growth of the dental lamina continues in an area called the "progress ...
In animal tooth development, cementogenesis is the formation of cementum, one of the three mineralized substances of a tooth.Cementum covers the roots of teeth and serves to anchor gingival and periodontal fibers of the periodontal ligament by the fibers to the alveolar bone (some types of cementum may also form on the surface of the enamel of the crown at the cementoenamel junction (CEJ)).

ZygoteBody, formerly Google Body, is a web application by Zygote Media Group that renders manipulable 3D anatomical models of the human body. Several layers, from muscle tissues down to blood vessels, can be removed or made transparent to allow better study of individual body parts. Most of the body parts are labelled and are searchable.
Anatomography is an interactive website which supports generating anatomical diagrams and animations of the human body. The Anatomography website is maintained by the DBCLS (Database Center for Life Science) non-profit research institute located at the University of Tokyo.
