DescriptionsTerm
The anterior-most pair of bones covering the brain, situated between the orbits. Actually paired, but often fusing together at an early age
The bone surrounding the foramen magnum and bearing the occipital condyles. Formed from 4 embryonic elements, the basioccipital below, 2 exoccipitals, and the supraoccipital above
Bone, if present, located just beneath the auditory bulla
Ivory-like substance beneath the enamel, usually constituting he bulk of a tooth
The portion of the skull anterior to the orbits
On the side next to the lips
Teeth with high crowns; usually rootless and ever-growing
Nipping or chiselling teeth at the front of the jaws
The bony roof of the mouth composed of parts of the premaxillary, maxillary and palatine bones
One of the two branches of the mandible
Extremely hard outer layer on the crown of a tooth. consiting of calcareous compounds
The arch of bone that forms the lateral border of the orbit and temporal fossa
cheek teeth with a cutting or shearing action adapted for a carnivorous diet
A vacant space, or gap, between teeth
A passage through which the tear duct drains into the nasal cavity, usually near the anterior margin of the orbit
A thin, median, vertical partition of bone that divides the nasal cavity into right and left halves
A ridge traversing the top or side of the braincase, marking the dorsal border of the insertion of the temporal muscle. They may be found on parts of the frontal and parietal bones
Low crownded squarish teeth, capped with enamel, and possessing four major cusps arranged in a rectangle (as in pigs and humans)
Skin membvrane extending between the hindlegs and frequently enclosing the tail - especially in bats
Small head or bony prominence on a bone
Condition found in the Didelphimorphia and Peramelina in which the lower jaw is not shortened and the anterior lower incisors are not greatly elongated
The most dorsal part of the mandible, the part of the vertical ramus dorsal and anterior to the condyle
Paired bones in the front of the upper jaw that bear the incisor teeth
The posterior teeth in the upper and lower jaws that are nondeciduous
A longitudinal median bony ridge dorsal to the braincase. Often formed by a coalescence of temporal ridges
A bone in the penis of certain mammals
A projection from either the jugal bone on the zygomatic arch, or the frontal bone, partially separating the orbit and the temporal fossa
The opening of the skull through which the spinal cord emerges
The bone that forms the midsection of the zygomatic arch
DescriptionsTerm
Pertaining to two or more digits that are fused together
The lower jaw bone, constituting one half of the lower jaw or mandible
With a pattern consisting of sharply angled triangles, or loops with sharp salient angles
The layer of bonelike material covering the root of a tooth
A perforation through a bone for the passage of a nerve or blood vessel
Paired bones that form the posterior part of the hard palate, and wall the anterior part of the interpterygoid fossa
Paired bones, sometimes fused to the basisphenoid and alisphenoids, that form the walls of the posterior part of the interpterygoid fossa
A hooklike spine on the posyterior cormer of the pterygoid bone
A bony or cartilaginous spur arising from the ankle, and in bats, helping to support the uropatagium
The projection from the lower medial margin of the pinna in most microchiropteran bats
On the side next to the tongue
Overlapping as the shingles of a roof
External ear
The bony external or anterior aperture of the nasal cavity
On the side next to the cheek
In bats, membrane that fills space between the digits of the forelimb: d. minus (between digits II and III), d. longus (between digits III and IV), d. latus (between digits IV and
An unpaired median bone in the floor of the interpterygoid fossa, with two lateral wings, sometimes called orbitosphenoids, that form part of each orbit
Lacking teeth
The trough in the squamosal bone for the reception of the mandibular condyle of the dentary
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
In bats, thin web of skin that extends from the shoulder to the wrist anterior to the upper arm and forearm
Deciduous teeth, posterior to the canines
Low-crowned; any tooth whose width exceeds the height of the crown above the alveolus
Having teeth differentiated into various types, i.e. incisors, canines, premolars, and molars
A transverse bony ridge across the cranium near the posterior border of the parietals
The internal or posterior bony opening(s) of the nasal cavity
A socket in which the root of a tooth is set
The large space between the orbit enclosed by the zygomatic arch and the postorbital processes
The bone in the upper jaw that bears the canine, premolar, and molar teeth
DescriptionsTerm
A pit, depession, trough, or extensive opening
The posterior ventral projection of the dentary below the condyle
The part at the rear of the mandible that articulates with the upper jaw
A small bone in the anterior face of the orbit
A passage from the anterior face of the orbit to the side of the rostrum, passing through the base of the maxillary process
A median ventral bone lying anterior to the occipital and between the auditory bullae
The bony socket that contains the eyeball
A fan-shaped bone on either side of the braincase above the auditory bulla
The lower jaw, composed of the two dentaries in mammals
The inflated bony capsule that encases the middle and inner ear
Having perforations or openings
Having a fringed or fringe-like border
Having two sets of teeth: a milk or deciduous set and then a permanent set
Paired bones roofing the posterior part of the braincase
A knob on either side of the foramen magnum that articulates with the first vertebra
An enlarged tooth between the incisors and premolars; usually a large stabbing tooth, occasionally bladelike, but sometimes small and similar to the teeth preceding it
An unpaired bone at the rear of the cranium located between the parietals and above and anterior to the occipital
Teeth whose crowns have a series of lophs
A winglike bone forming part of the lateral wall of the braincase. It also forms part of the posterior wall of the orbit. Frequently fused to the basisphenoid
The first digit of the pes (foot), the big toe; frequently opposable in arboreal mammals
Chamber into which digestive, reproductive and urinary systems empty, and then exit the body
Bone surrounding the middle ear cavity
A pair of openings piercing the palate behind the incisor teeth
The suture between the paired dentaries
Having teeth that are all essentially similar, usually simple cones
A transverse ridge of enamel across a tooth
Teeth with longitudinal crescentic ridges of enamel
A bony bar between the orbit and the temporal fossa, formed by the union of the two postorbital processes
