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
