Vermilion zone

each lips vermilion zone has a darker appearance than the surrounding skin. #5

Regions of the neck

extend front the skull and lower jaw down to the clavicles and sternum

Philtrum

extends downwards from the nasal septum to the midline of upper lip. The philtrum terminates in a thicker area of the midline of the upper lip. #8

The main feature of the nasal region is the:

external nose (actual nose)

buccal

facial structures close to the cheeks

labial

facial structures closet to lips

Name the regions of the face:

frontal, orbital, nasal, infraorbital, buccal, oral, mental, and zygomatic

Orbital region

includes the eyeball and its supporting structures of the orbit. #6

Frontal region

includes the forehead and the area superior to eyes. #1

Naris, nares is plural (nostril)

inferior to the apex on each side of the nose

Temporomandibular Joint (TMJ)

inferior to the zygomatic arch and just anterior to the external ear. This is where the upper skull forms a joint with the lower jaw. (you can feel it by putting finger in ear and opening/shutting mouth)#2

Parotid papilla

inner part of the buccal mucosa just opposite the maxillary second molar is this small elevation. Protects the opening to the parotid duct. I

Labial frenum (plural frena)

is a fold of tissue located at the midline between the labial mucosa and the alveolar mucosa on the upper and lower dental arches.

Masseter muscle

is felt when a patient clenches the teeth together. #3

Upper cheek

is fleshy, mainly formed by a mass of fat and muscle

Root of the nose

is located between the eyes and the apex of the nose

Infraorbital region

is located inferior to the orbital region and lateral to the nasal region. #5

Coronoid process

is where the anterior thin, sharp border of the ramus terminates. #14

Sternocleidomastoid muscle (SCM)

large strap muscle, located on each side of the neck and is used for dividing the neck into further regions. #5

Zygomatic region

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

palatal

lingual structures closet to the palate

The ____ of the face mark the anterior boundary of the oral cavity, and the ______ is the posterior boundary. The _____ of the face mark the lateral boundaries, and the _____ marks the superior boundary. The ____ of the mouth is the inferior border of the oral cavity.

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

Lips

are the fleshy folds the mark the gateway of the oral cavity proper.

Orbit

bony socket

Submandibular salivary gland

can be palpated in the neck region B

sublingual salivary gland

can be palpated in the neck region A

Vertical dimension of the face

Face divided into thirds

Fordyce's spots

Small yellowish elevations that may appear on the buccal mucosa

Alvelor mucosa

The redder mucosa located inferior to the mandible gingiva and superior to the maxillary gingiva. L

Tubercle of the upper lip

The thicker area of the upper lips where the philtrum terminates. #2

Mucobuccal fold

The tissue at the junction between the labial or buccal mucosa and the alveolar mucosa is the

Larynx

The voice box; located in the top part of the trachea, underneath the epiglottis.

Coronoid notch

a concave forward curve formed by the anterior border of the ramus #13

Thyroid gland

an endocrine gland, can also be palpated within the midline cervical area. Located inferior to the thyroid cartilage, at the junction between the larynx and trachea.
