The crown is large and conical, very convex on its labial surface, a little hollowed and uneven on its lingual surface, and tapering to a blunted point or cusp, which projects beyond the level of the other teeth. The root is single, but longer and thicker than that of the incisors, conical in form, compressed laterally, and marked by a slight ...
The Humane Society of Harford County, Inc. (HSHC) is a nonprofit open admission animal shelter located in Fallston, Maryland, contracted with the Harford County Government to provide sheltering services for all animals brought to HSHC by Animal Control (which is operated under the Harford County Sheriff's Office) as stray, or subjects of animal cruelty or neglect cases.
A toothcomb (also called a tooth comb or dental comb) is a dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in lemuriform primates (which include lemurs and lorisoids), treeshrews, colugos, hyraxes, and some African antelopes.
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [3] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [2] The dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...
A young adult horse will have teeth which are 4.5-5 inches long, with the majority of the crown remaining below the gumline in the dental socket. The rest of the tooth will slowly emerge from the jaw, erupting about 1/8" each year, as the horse ages.
A tooth (pl.: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food.Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young.
The mouth cone ("everted pharynx") of a possible new species of Meiopriapulus, a marine worm in the Priapulida, bears pharyngeal teeth. [5] Fossils of the Yunnanozoon and Haikouella possess pharyngeal teeth. The lower pharyngeal bones of cichlids also carry specialized teeth which augment their normal mandibular teeth in the breakdown of food.
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [2] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [1] Mesenchymal cells within the dental papilla are responsible for formation of tooth pulp.
