More caudally, at the angle of the jaw, this thin plate of bone expands medially and laterally into two thick bony protrusions that are roughened to allow muscle attachment (Fig. 5.33). These protrusions reduce in size towards the dorsal border of the vertical ramus. These normal roughened...
SummaryWe investigated the tooth pattern on the lower jaw of adult farmed Atlantic salmon (Salmo salar L.) to elucidate whether this pattern is more regular, with less variations, than that observed in wild Atlantic salmon studied previously. A highly regular and predictable tooth pattern, in ...

tooth formation is stimulated at least two, three, four, five or six sites in the jaw (either in the maxilla (upper jaw) or in the mandible (lower jaw) or both).
1.Any of the hard bony structures in the mouth used to grasp and chew food and as weapons of attack and defense. In mammals and many other vertebrates, the teeth are set in sockets in the jaw. In fish and amphibians, they grow in and around the palate. See alsodentition. ...
Immediately after dissection the lower jaw was immersed in RNA later (Qiagen), cut into small pieces of a 2–5 mm each, then frozen in liquid nitrogen. Samples were transferred into homogenization tubes containing 2.8-mm ceramic beads and 2 mL of RLT solution (Qiagen). Tissues were disrupted...
a The heatmap summarizing the frequency of functional tooth loss in each position in three groups; and b-d the frequency of functional tooth loss in each position among people who lost ≤12, 13–16, and > 16 functional teeth, where the upper and lower panel shows the frequency of ...
Estimations were made presuming isometry from values obtained in a jaw model of a 240 kg great white shark specimen (i.e., anterior and posterior bite forces of 1602 N and 3131 N, respectively)66. The arithmetic average of anterior and posterior force values was considered as the force ...
Short of having almost any of that information, it seems you are describing a tooth that has very advanced tooth decay: 1) It’s at a point where its structurally unsound enough that portions have started to fragment off (here’s our page aboutbroken teeth). So much of the tooth is now...
a: upper jaw incisors. b: lower jaw incisor. Triadan position assigned to the tooth length. Box: interquartile range (25%, 75%), horizontal line: median, center point: mean, whiskers: range (5%, 95%), stars: minimum and maximum. Lower-case characters (a, b) indicate a significant ...
