OralMucosa.txt

• buccal, labial, alveolar, floor ofmouth, ventral tongue surface, soft palate
• soft, moist, able to strech and compress, cushion
• nonkeratineized epithelium wiwth smooth interface
• few rete ridges
• CT papillae with elastic fibers in the lamina propria and submucosa

• Attached gingiva, hard palate, dorsal tongue surface
• Rubbery surface texture and resiliency, serving as a firm base
• Keritinized epithelium and interdigitated interface
• many rete ridges
• CT papillae with thin layer of submucosa or none

• dorsal tongue surface
• lingual Papillae
• discrete structures of lamina propria and epithelium

• immature form of orthokeratinization

tissue response to friction or trauma

• Most common on body
• fine-pointed cones giving velvety texture
• thick layer of keritinized epithelium
• NO TASTE BUDS
• mechanical

• lesser numbers
• mushroom shaped small red dots
• thin layer of keritinized epithelium
• taste buds superficial
• TASTE

• 4-11 vertical ridges on lateral surface of posterior tongue
• leaf shaped
• keritinized epithelium w taste buds superficial
• TASTE

• 7-15 large raised mushroom-shaped structures anterior to sulcus terminalis
• similar histo to fungiform, deep to tongue surface, taste buds in base surrounded by trough
• von Ebner's minor salivary glands in submucosa
• TASTE

Minor serous salivary glands that flush trough around the circumvallate papilla to improve taste discrimination

• Attachment of the Gingival Tissue to Tooth by Hemidesmosomes

• Largest, encapsulated
• parotid duct (Stenson's) max 2nd molar buccal mucosa
• Short Striated ducts
• Long intercalated ducts
• Mainly serous Acini

• Intermediate, encapsulated
• Submandibular duct (Wharton's) near lingual frenum on floor of mouth
• Long striated ducts
• Short intercalated ducts
• Serous and mucoserous acini

• smallest, no capsule
• Sublingual duct(Bartholin's) same area as submandibular, may have additional ducts in submandibular folds
• rare or absent striated ducts
• absent intercalated ducts
• mainly mucous with some mucoserous acini
