Facial Structures/Oral Cavity Flashcards
-Define and pronounce all terms -Locate and identify regions and associated landmarks on diagram and clinically -Describe boundaries of oral cavity -Relate the structures of the oral cavity with their description or label
Frontal
Fore head region. Executive Function/Judgement
Occipital Region
Back and bottom of head
Temporal
By the temple
Zygomatic
Above cheekbone where you would apply highlighter or bronzer
Buccal (buckle)
Cheek. UNDER zygomatic
Infraorbital
Below eye region
Nasal
Nose
Orbital region
Eyes
Oral region
Mouth
Mental region
Chin
Frontal eminence
Spot on forehead that sticks out a bit further than the rest of the forehead
Glabella
Skin surface landmark between the eyebrows
Nasal Region
Contains Nasion which is the bony landmark where the nasal and frontal bones meet.
Root of nose
The deepest dip at the top of nose by the eyes
Apex
Tip
Septum
Cartilage in nose that separates the nose into right and left nostrils
Temporomandibular Joint
Condyle of the mandible articulates with the glenoid fossa of the temporal bone.
- Allows movement of lower jaw (mandible)
- Located anterior to the tragus
Commisure
Corner (of mouth)
Vermillion
All the pink part of the lips (place that needs chapstick)
Maxilla
Upper Jaw/arch
Mandible
Lower jaw/arch
Lingual
Towards tongue
Buccal
Towards cheek
Palatal
Towards/on palate
Facial
Towards cheek
Labial
Towards lips
Oral Cavity
Inside of mouth
Mucosa
Mucous membrane lining the oral cavity
Gingiva
Gums (firm, pink mucosa in healthy mouth)
Parotid Papilla***
Buccal mucosa that looks like bump that saliva dumps out of into the mouth. Contains Stensons duct
Attached Gingiva
Gingiva that tightly adheres to the bone around the roots of the teeth (makes chewing possible)
Marginal gingiva
Non-attached, at the gingival margin (most cervical portion) ex. where popcorn gets stuck
Sulcus
Inner surface of marginal gingiva (space between the teeth)
Interdental gingiva (Interdental papillae)
Gingiva between the teeth (where you floss around the triangle)
Vestibules
Upper and lower spaces between the cheeks, lips, gums. Above/below the alveolar mucosa
Alveolar Mucosa
Thinner, redder mucosa overlying the “alveolar process”: toother-bearing portion of each jaw bone
Mucogingival Junction
Line of demarcation between the alveolar mucosa and gingiva
Raphe
Tissue line
Suture
Bone line
Median palatine raphe
Midline ridge of TISSUE on hard palate
Palatine rugae
Firm, irregular ridges of tissue radiating out from the raphe and incisive papilla
Incisive Papilla
Small bulge of tissue at the most anterior portion of the hard palate (overlies incisive canal)
Filiform
Most number type on tongue. Hair like appearance.
Fungiform
Little pink dots, contains taste buds, not as many
Foliate
Not much of a function. Lateral borders, vertical leaf like appearance on side of the tongue. Hard to see.
Cirucumvallate
Divides anterior 2/3 and posterior 1/3.
10-14, lined up anteriorly to the sulcus terminalis
Dorsal Tongue
Top of tongue
Ventral Tongue
Bottom of tongue
Deep Lingual Veins
Visible large blood vessels, pass close to the surface
Plicae Fimbriata
Folds of the tissue just lateral to the lingual veins, can have fringelike projections
Lingual Frenum
Attaches tongue to FOM
Sublingual Fold
V-shaped, contains ducts for sublingual salivary glands
Sublingal carruncle
Contains openings of the submandibular and sublingual ducts (Whartons Duct). Where we gleek from because the ducts empty.
Ankyloglossia
Tongue Tied
Tonsilar Stones
Food is trapped and lymph tries to get them out by growing to push them out
Nasion***
Midpoint landmark located at the junction of the frontal and nasal bones. Bony Landmark. See Slide #18
