Philtrum
Definition
vertical groove between nose and tubercle of upper lip
Term
Tubercle of Upper Lip
Definition
bulge on vermillion region below philtrum
Term
Labiomental Groove
Definition
sulcus/horizontal wrinkle between lower labial and chin
Term
Labial Commissures
Definition
corners of mouth
Term
Divisions of Oral cavity
Definition

Vestibules - Labial & Buccal

Labial vesibule- canine to canine

Buccal vestibule- premolar to wisdom

 

Oral Cavity Proper- inside mouth

Term
Subclasses of Oral Mucosa
Definition

Masticatory mucosa

 

Specialized mucosa

 

Lining mucosa

Term
Masticatory mucosa
Definition
gingiva and hard palate
Term
Specialized mucosa
Definition
dorsal and posterior lateral surfaces of the tongue
Term
Lining mucosa
Definition

floor of mouth

ventral of tongue

alveolar mucosa

vestibular mucosa

soft palate

Term
4 Components of Periodontium
Definition

Gingiva

Cementum

Periodontal ligament

Alveolar bone

Term
Retromolar pad
Definition

behind last mandibular molars

dense spongy tissue

Term
Pterygomandibular Raphe
Definition
runs from mandible to pterygoid notch on sphenoid bone
Term

Pharyngeal tonsil

(Adenoids)

Definition
between nasopharynx and oropharynx
Term

Tongue

(2 divisions separated by terminal sulcus)

Definition

Anterior 2/3's

 

Posterior 1/3

Term

Anterior 2/3's

 

Dorsal surface

Definition

Papillae

 

Filiform- rough, most numerous, moves food around

 

Fungiform- red dots, taste buds

 

Circumvallete (vallate)- sit right in from of terminal sulcus

 

Terminal sulcus- separates 2/3's from 1/3's tongue

Term

Anterior 2/3's

 

Lateral surface

Definition
foliate papillae- red, taste buds
Term

Anterior 2/3's

 

Ventral surface

Definition

Lingual frenum

 

Lingual Veins- blue lines on bottom of tongue

Term
Posterior 1/3 of tongue
Definition
Lingual tonsil- lymphoid tissue
Term
What does the floor of the mouth consist of?
Definition

Lining mucosa

 

Sublingual ridges (folds)- caused by sublingual salivary glands

 

Sublingual caruncles- different sizes/where saliva comes out, salivary duct empties

Term
Salivary glands
Definition

Parotid gland

(Stensen Duct)

 

Submandibular gland

(Wharton's Duct)

 

Sublingual gland

(Bartholin's duct)

Term
Fauces
Definition
opening into pharynx from oral cavity
Term
Functions of saliva
Definition

keeps mucosa moist

moisten food to aid in swallowing

cleansing

flush food debris

digestion

immunity

antibodies and enzymes

taste

Term
Two types of saliva
Definition

serous- runny

 

mucous- think

Term

Parotid gland

 

Definition

serous saliva

 

by mandible angle

 

duct- main parotid or Stensen's duct

 

orifice- parotid papilla

Term
Submandibular gland
Definition

mixed saliva/mostly serous

 

under mandible

 

Duct- Wharton's duct

 

Orifice- sublingual caruncle

 

produces the most saliva of any major gland

Term
Sublingual gland
Definition

mixed but mostly mucous saliva

 

Ducts- Bartholin's duct---> empties into Wharton's duct

also has major and minor ducts into floor of mouth

 

Orifice- sublingual caruncle

Term
Free gingiva
Definition

also called "marginal gingiva" because it forms a cuff around tooth

 

the very edge is often referred to as the gingival margin

Term
Interdental gingiva
Definition

col-base is attached to interproximal bone crest (between papilla under contact)

 

sides form interproximal marginal gingiva

Term
Attached gingiva
Definition

demarcated from free gingiva and papilla by the "free gingival sulcus"

 

named this b/c it is firmly attached to cementum and periosteum of bone by connective tissue fibers

Term
Vestibular mucosa
Definition

alveolar mucosa and labial/buccal mucosa

 

covers alveolar bone, lips, and cheeks

 

freely movable mucosa forming the vestibules

Term
Frena/Frenulum
Definition

labial- maxillary and mandibular

 

buccal- max R, max L, mandib R, mandib L

Term
Hard Palate
Definition

tissue that has palatal bone underneath

 

1. Rugae- folds-holds food

2. mid-palatine raphe- down middle of palate, soft tissue where right and left sides join

3. incisive papilla- behind front teeth (nerve fibers)

4. maxillary tuberosity- knob behind last molar on top

Term
Soft Palate
Definition

for swallowing and phonetics

 

fovea palatinae- 2 tiny depressions in center

 

uvula- hangs down, muscle inside

closes off nasal cavity

Term
Glossopalatine arch
Definition

anterior tonsilar pillar

 

soft palate to base of tongue

Term
Pharyngopalatine arch
Definition

posterior tonisallar pillar

 

soft palate to pharynx

 

posterior border of oral cavity

Term
Palatine tonsil
Definition

or tonsilar niche

 

lymphatic tissue- defense/immunity/protection

Term
Minor salivary glands
Definition

keep mucosa moist

 

mostly mucous

 

locations are where you have lining mucosa
