A diagram of generalized tribosphenic molars with notable features labelled. Upper left molar in pink, lower left molar in blue. Mesial (forwards) is to the left. Teeth are depicted in left lateral view (left side and center of the image) or occlusal view (right side of the image).
Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as ...
Anatomy of rabbit teeth. The incisors and cheek teeth of rabbits are called aradicular hypsodont teeth. Aradicular teeth never form a true root with an apex, and hypsodont teeth have a high crown to root ratio (providing more room for wear and tear). [4] This is sometimes referred to as an elodont dentition, meaning ever-growing.
Beavers are associated with activity and environmental engineering. If you are “as busy as a beaver,” you are getting things done. These aquatic rodents spend most of their time in the water ...
The trademark sharp front teeth of both species pose a particular danger, as they are long enough to pass through limbs and cause significant bleeding. [ 4 ] At least one beaver attack on a human is known to have been fatal: a 60-year-old fisherman in Belarus died in 2013 after a beaver bit open an artery in his leg. [ 3 ]
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.
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
