glabella
A single bony prominence of the frontal bone located between the superciliary arches in the inferior part of the frontal bone above the root of the nose.
cartilage
A specialized type of dense connective tissue; attached to the ends of bones and forming parts of structures, such as the nasal septum and the framework of the ear.
dental prognathism / buck teeth
Oblique insertion of the teeth; front teeth protrude
Cribiform plate
The horizontal plate of the ethmoid bone separating the cranial cavity from the nasal cavity.
mandible
The horseshoe-shaped bone forming the inferior jaw.
Angle of the mandible
a bony angle formed by the junction of the posterior edge of the ramus of the mandible and the inferior surface of the body of the mandible
Alveolar process
a bony ridge found on the inferior surface of the maxilla and the superior surface of the mandible which contains the sockets for the teeth
Infranasal prognathism
a form of prognathism in which the base of the nasal cavity protrudes abnormally
maxilla
a paired bone with several processes that form the skeletal base of most of the superior face, roof of the mouth, sides of the nasal cavity, and floor of the orbit
condyle
a rounded prominence at the end of a bone forming an articulation; the posterior process of the ramus of the mandible
mental eminence
a triangular projection on the interior portion of the anterior mandible
Alveolar prognathism
an abnormal protrusion of the alveolar process
face
anatomically, the region from the eyes to the base of the chin; physiognomically, the region from the normal hairline to the base of the chin.
hard palate
anterior portion of the roof of the mouth
vomer
bone of the nasal cavity situated between the nasal passages on the median plane; it forms the inferior and posterior portion of the septum of the nose
zygomatic bone / zygoma / malar
bones of the cheek
nasal bones
directly inferior to the glabella and forming a dome over the superior portion of the nasal cavity
temporal bone
form the inferior portion of the sides and base of the cranium; inferior to the parietal bones and anterior to the occipital bone
occipital bone
lowest part of the back and base of the cranium, forming a cradle for the brain
buccal depression
natural, shallow concavities of the cheeks which extend obliquely downward from the medial or lateral margins of the cheekbones
zygomatic arch depression
one of the lesser concavities of the face located on the lateral portion of the cheek inferior to the zygomatic arch
frontal eminences
paired, rounded, unmargined prominences of the frontal bone found approximately one inch beneath the normal hairline
occipital protuberance
prominence at the center of the external surface of the occipital bone
mandibular prognathism
protrusion of the inferior jaw
maxillary prognathism
protrusion of the superior jaw
lines of the temple
slightly raised, curved ridges located at the boundary between the forehead and the temple region; marks the lateral border of the forehead
frontal bone
the anterior third of the cranium, forming the forehead and the anterior portion of the roof of the skull
coronoid process
the anterior, non-articulating process of the ramus of the mandible which serves as the insertion for the temporalis muscle.
bridge of the nose
the arched portion of the nose which is supported by the nasal bones
parietal bones
the bones that form the roof and part of the sides of the skull
orbital cavity / eye socket
the bony region containing the eyeball
temporal cavity
the concave surface of the head overlying the temporal bone
incisive fossa
the depression between the mental eminence and the inferior incisor teeth.
columna nasi
the fleshy termination of the nasal septum at the base of the nose; located between the nostrils; the most inferior part of the mass of the nose
body of the mandible
the horizontal portion of the lower jaw
supercilliary arches
the inferior part of the forehead just superior to the median ends of the eyebrows
foramen magnum
the opening in the occipital bone through which the spinal cord passes
external auditory meatus
the opening or passageway of the ear
nasal cavity
the orifice in the bony face bounded by the margins of the nasal bones and the maxilla
cranium
the part of the skull which encloses the brain
zygomatic arch / process
the processes on the temporal and zygomatic bones; determines the widest part of the face
parietal eminence
the rounded peak of the external convexity of the parietal bones; determines the widest part of the cranium
mastoid process
the rounded projection on the inferior portion of the temporal bones just posterior to the lobe of the ear
Nasal spine of the maxilla
the sharp, bony projection located medially at the inferior margin of the nasal cavity.
mandibular fossa
the small oval depression on the zygomatic process of the temporal bone into which the condyle of the mandible articulates, just anterior to the external auditory meatus.
buccal cavity
the space between the lips and the gums and teeth; the vestibule of the oral cavity
supra-orbital margin
the superior rim of the eye socket
crown / vertex
the topmost part of the head
squama
the vertical surface of the temporal bone
septum
vertical cartilage dividing nasal cavity into two chambers, responsible for asymmetry of the nose
ramus
vertical portion of the mandible
