Oral Cavity
Inside of mouth
28
Mucosa
Mucous membrane lining the oral cavity
29
Gingiva

30
Parotid Papilla***
Buccal mucosa that looks like bump that saliva dumps out of into the mouth. Contains Stensons duct
31
Attached Gingiva
Gingiva that tightly adheres to the bone around the roots of the teeth (makes chewing possible)
32
Marginal gingiva
Non-attached, at the gingival margin (most cervical portion) ex. where popcorn gets stuck
33
Sulcus
Inner surface of marginal gingiva (space between the teeth)
34
Interdental gingiva (Interdental papillae)
Gingiva between the teeth (where you floss around the triangle)
35
Vestibules
Upper and lower spaces between the cheeks, lips, gums. Above/below the alveolar mucosa
36
Alveolar Mucosa
Thinner, redder mucosa overlying the "alveolar process": toother-bearing portion of each jaw bone
37
Mucogingival Junction
Line of demarcation between the alveolar mucosa and gingiva
38
Raphe
Tissue line
39
Suture
Bone line
40
Median palatine raphe
Midline ridge of TISSUE on hard palate
41
Palatine rugae
Firm, irregular ridges of tissue radiating out from the raphe and incisive papilla
42
Incisive Papilla
Small bulge of tissue at the most anterior portion of the hard palate (overlies incisive canal)
43
Filiform
Most number type on tongue. Hair like appearance.
44
Fungiform

45
Foliate
Not much of a function. Lateral borders, vertical leaf like appearance on side of the tongue. Hard to see.

50
Plicae Fimbriata
Folds of the tissue just lateral to the lingual veins, can have fringelike projections
51
Lingual Frenum
Attaches tongue to FOM
52
Sublingual Fold
V-shaped, contains ducts for sublingual salivary glands
53
Sublingal carruncle
Contains openings of the submandibular and sublingual ducts (Whartons Duct). Where we gleek from because the ducts empty.
54
Ankyloglossia
Tongue Tied
55
Tonsilar Stones
Food is trapped and lymph tries to get them out by growing to push them out
56
