  • Front
  • Back
Ankylosis
Union of separate bones or hard parts to form a single bone or part
Anthropoid
A person resembling an ape
Antrum
An anatomical cavity within a bone (as the maxilla) or hollow organ (as the stomach)
Apex
the highest or culminating point
Alveolus
a small cavity or pit: as a: a socket in the jaw for a tooth
Bovine
having qualities (as placidity or dullness) characteristic of oxen or cows
Brachyodont
Tapirs have brachyodont, or low-crowned, teeth that lack cement
Buccal
cheek
Bunodont
low crownded squarish teeth, capped with enamel, and possessing four major cusps arranged in a rectangle (as in pigs and humans).
Canine
one of the four pointed conical teeth (two in each jaw) located between the incisors and the premolars
Carnassial
a tooth that is used to cut or shear flesh and bone. The carnassial teeth of flesh-eating animals include the last premolar on either side of the upper jaw and the first molar on either side of the lower jaw
Carnivore
an animal that eats other animals
Cervix
The lower section of the uterus which protrudes into the vagina and dilates during labor to allow the passage of the fetus
Cetacea
An order of Mammalia, including the Whales, Dolphins, etc., having the form of the body fish-like, the skin naked, and only the fore limbs developed.
Chiroptera
"hand-wing;" the scientific order that bats belong to
Cingulum
A prominent girdle around the base of a crown of a tooth just above the alveolus.
Confluent (orbits and zygomatic arches)
joined together
Continuously Erupting
Continuously Erupting
Cribriform
perforated with small apertures like a sieve.
Crypt
a combining form meaning hidden or concealed, or denoting relationship to a crypt.
Cuticle (cuticular)
In animals, a multilayered, extracellular, external body covering, usually composed of fibrous molecules such as chitin or collagen, and sometimes strengthened by the deposition of minerals such as calcium carbonate.
Deciduous
describes trees that undergo the annual loss of all leaves, characteristic of trees such as maple, ash, cherry, and cypress.
Dentine (various types)
Dentin (BE: dentine) is the name of substance between the enamel (crown) or cementum (root) of a tooth and the pulp chamber. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water. Because it is softer than enamel, it decays more rapidly and is subject to severe caries if not properly treated
Diastema
the gap between incisors or canines and cheek teeth in mammals
Diprotodont (marsupials)
condition that exist in the Paucituberculata and Diprotodonta. The lower jaw is shortened and the first lower incisors are greatly elongated to meet the upper incisors.
Distal
Back
Diphyodont
Having two sets of teeth: milk (deciduous) and permanent; the condition of most mammals
Edentata
A peculiar order of quadrupeds, characterised by the absence of at least the middle incisor (front) teeth in both jaws
Embrasure
the space between two adjacent teeth
Enamel
hard white substance covering the crown of a tooth
Enameloid
a form of bone with even greater density and mineralization than dentine, usually found as a superficial layer over a dentine structure (eg scales of Paleozoic fish); mesodermal derivative laid down at outer surface of mesodermal papillae; may be up to 25% organic material.
Equidae (equine)
the scientific name for the family to which horses and their relatives belong. Asses, donkeys, zebras, mules, ponies, and horses are all a part of this family
Eutheria
all mammals except monotremes and marsupials
Felidae (feline)
Cat-family
Follicle
The fluid-filled sac in the ovary that nurtures the ripening egg and from which the egg is released during ovulation.
Foramen
A hole in a bone usually for the transmission of blood vessels and/or nerves
Fossa
A pit, depression, or concavity, on a bone, or formed from several bones.
Haplodont
teeth have simple crowns and roots, as seen in the dolphin.
Herbivores
Animals that eat only plants.
Heterodont
having teeth differentiated into various types, ie incisors, canines, premolars, and molars.
Homodont
having teeth that are all essentially similar, usually simple cones (secondary homodonty in odontocete whales)
Hypsodont
teeth with high crowns; usually rootless and ever-growing.
Incisor
Any of the four front teeth in either the upper or lower jaw.
Insectivora
shrews; moles; hedgehogs; tenrecs
Lacuna
small pit or cavity.
Lagomorphs
“hare-shaped” animals such as rabbits, hares, and pikas.
Lophodont
Cheek teeth that have a complex, folded cusp pattern, providing grinding surface area for herbivory (eg black rhinoceros)
Mandible (mandibular)
The lower jaw, composed of the two dentaries in mammals.
Marginal ridge
the rounded borders that form the mesial and distal margins of the occlusal surface of a tooth.
Marsupials
An order of Mammalia in which the young are born in a very incomplete state of development, and carried by the mother, while sucking, in a ventral pouch (marsupium), such as the kangaroos, opossums, etc
Masticatory
increases flow of saliva upon chewing
Maxilla
The maxilla is the major bone of the upper jaw
Mesial
Centre
Metatherian
primitive pouched mammals found mainly in Australia and the Americas
Monophyodont
Having only one set of teeth
Occlusal
The biting/chewing surface of the back teeth.
Piscivores
Fish-eaters; those organisms that subsist exclusively or primarily on fish.
Polyphyodont
having more than two sets of teeth in a lifetime, as opposed to diphyodont.
Polyprotodont (marsupials)
having more than two lower incisors.
Premolar
One of the two permanent teeth located in front of the molars and behind each cuspid. These teeth have two cusps (points) and are used to tear and grind food.
Primates
An order within class Mammalia. Large-brained arboreal mammals with stereoscopic color vision and grasping hands (and sometimes feet). Includes prosimians, monkeys, apes, and hominids
