Frontal region of the face

forehead and the area above the eyes

Frontal Region

region of the face that includes the forehead and area above the eyes

Orbital region

facial region that includes bony orbit and eyeball

Nasal region

region of the face occupied by external nose

External nose

surface of the nose in the nasal region

Root of the nose

nose located between the eyes

Apex of the nose

tip of the nose

Naris/Nares

nostril(s) of the nose

Nasal Septum

midline part of the nose that separates the nares

Ala/Alae

winglike cartilaginous structure/s bounding nares laterally

Infraorbital region

facial region located both inferior to the orbital region and lateral to the nasal region

Infraorbital region location

Zygomatic region

facial region that overlies zygomatic arch

Zygomatic arch

bony support for cheek

region of the face composed of the soft tissue of cheek

Masseter muscle

powerful bilateral muscle of mastication

Angle of the mandible

thickened area on posterior-inferior border of mandibular ramus

Parotid salivary gland

major salivary gland located irregularly from the zygomatic arch to the posterior border of the mandible

Palpate

examine by touch, feeling with the fingers or hands during a physical examination

Oral region

region of face that contains the lips and oral cavity

Vermilion zone

darker appearance of the lips with its outlining mucocutaneous junction at the vermillion border as compared with surrounding skin

Mucocutaneous junction

transition zone at the vermilion border outlining the lips from the surrounding skin

Philtrum

Labial commissure

corner of the mouth where the upper and lower lips meet

Mental region

region of the face with the chin as the major feature

Mandibular symphysis

midline area of mandible marking fusion of the two mandibular processes

Ramus/Rami

mandibular plate/s that extend/s upward and backward from the body on each side

Coronoid process

bony projection at anterior border of mandibular ramus

Coronoid notch

main part of anterior border of mandibular ramus

Mandibular condyle

bony projection off posterior and superior border of mandibular ramus

Mandibular notch

depression between coronoid process and condyle
