Vestibules - Labial & Buccal

Labial vesibule- canine to canine

Buccal vestibule- premolar to wisdom

Oral Cavity Proper- inside mouth

Masticatory mucosa

Specialized mucosa

Lining mucosa

floor of mouth

ventral of tongue

alveolar mucosa

vestibular mucosa

soft palate

Gingiva

Cementum

Periodontal ligament

Alveolar bone

behind last mandibular molars

dense spongy tissue

Pharyngeal tonsil

(Adenoids)

Tongue

(2 divisions separated by terminal sulcus)

Anterior 2/3's

Posterior 1/3

Anterior 2/3's

Dorsal surface

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

Anterior 2/3's

Lateral surface

Anterior 2/3's

Ventral surface

Lingual frenum

Lingual Veins- blue lines on bottom of tongue

Lining mucosa

Sublingual ridges (folds)- caused by sublingual salivary glands

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

Parotid gland

(Stensen Duct)

Submandibular gland

(Wharton's Duct)

Sublingual gland

(Bartholin's duct)

keeps mucosa moist

moisten food to aid in swallowing

cleansing

flush food debris

digestion

immunity

antibodies and enzymes

taste

serous- runny

mucous- think

Parotid gland

serous saliva

by mandible angle

duct- main parotid or Stensen's duct

orifice- parotid papilla

mixed saliva/mostly serous

under mandible

Duct- Wharton's duct

Orifice- sublingual caruncle

produces the most saliva of any major gland

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

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

the very edge is often referred to as the gingival margin

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

sides form interproximal marginal gingiva

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

alveolar mucosa and labial/buccal mucosa

covers alveolar bone, lips, and cheeks

freely movable mucosa forming the vestibules

labial- maxillary and mandibular

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

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

for swallowing and phonetics

fovea palatinae- 2 tiny depressions in center

uvula- hangs down, muscle inside

closes off nasal cavity

anterior tonsilar pillar

soft palate to base of tongue

posterior tonisallar pillar

soft palate to pharynx

posterior border of oral cavity

or tonsilar niche

lymphatic tissue- defense/immunity/protection

keep mucosa moist

mostly mucous

locations are where you have lining mucosa
