Zygomatic region

lateral to the infraorbital region and contains the arch of the cheek (zygomatic arch) #6

palatal

lingual structures closet to the palate

lips; pharynx (throat); cheeks; palate; floor

Hyoid bone

located at the anterior midline in the neck, where it is suspended. Many muscles are attached to the hyoid bone, which controls the position of the base of the tongue.

Thyroid cartilage

located in the anterior midline, inferior to the hyoid bone. Is the prominence of the larynx. A

Parathyroid glands

located posterior to the thyroid gland and can not be palpated.

The loss of the vermilion border could indicate:

loss due to scar tissue, cellular changes (cancer), traumatic incidents, developmental disturbances. May be due to cleft lip.

The ________ consist of two ___________ bones that are sutured together during development.

maxilla; maxillary

Oral region

of the face has many structures within it. such as the lips and oral cavity

Oral mucosa (mucous membrane)

oral vestibules are lined by this

Mandibular condyle

projection extending from the angle of ramus with its next. #8

Nasal septum

separates the nares as a midline (can't be seen externally)

Golden proportions of face

set of guidelines for functional and aesthetic purposes that measures the vertical dimension of the face

Parotid salivary gland

small part that can be palpated in the buccal region as well as zygomatic region. Located irregularly from the zygomatic arch down to the posterior border of the lower jaw. C

maxillary and mandibular vestibules

space in the oral cavity between the lips and cheeks anteriorly and laterally and the teeth and their soft tissue medially and posteriorly. C

facial

structures closet to facial surface

lingual

structures closet to the tonngue

Zygomatic arch

the bony support for the cheek, extends from just below the lateral margin of the eye towards the middle part of the ear. #1

Parotid duct (Stenson's duct)

the duct of the parotid salivary gland.

Ramus (plural, rami)

the flat plate on the lateral side of mandible, extends upward and backward from the body of the mandible on each side. #6

Labial mucosa

the inner parts of the lips (pink color). J

Mandible

the lower jaw underlying the lower lip

Mandibular symphysis

the midline of the chin or mental region

Vermilion border

the outline of the lips from the surrounding skin by a transition zone. #7

Articulating surface of the condyle

the oval head involved in the TMJ #16

Angle of the ramus

the posterior border of the ramus extends from here to the mandibular condyle #7

Mastication

the process of chewing

Angle of the mandible

the sharp angle of the lower jaw inferior to the earlobe #4

Apex of the nose

the tip of the nose

Labial commissure

the upper and lower lips meet at each corner of the mouth #6

Maxilla

the upper jaw underlying the upper lip (bone includes body and 4 processes)

The oral cavity is divided into the.....

vestibules, jaws, and alveolar processes, teeth, and oral cavity proper.

Vestibular fornix

where the pink labial mucosa or buccal mucosa meets the redder alveolar mucosa at the mucobuccal fold.

Linea alba

white ridge of calloused tissue that extends horizontally at the level where the maxillary and mandibular teeth come together and occlude. (can be seen on tongue too)

Ala, alae plural

winglike cartilaginous structures that bound the nares laterally.

Mandible

The bone underlying the mental region (lower jaw) picture highlights the body area of the mandible.

Mental region

The chin is its main feature. #11
