Oral Mucosa Flashcards
(22 cards)
Give 5 functions of the oral mucosa
-Protection - Mechanical
-Infection, Immunity
-Sensation
-Secretion
-Absorption
-Thermoregulation (only in some species- not humans)
When would sensation and protection work together?
Food too hot, solid, tastes different
What substances can be absorbed by the oral mucosa?
Fluoride in toothpaste can be absorbed into sublingual area
What substances can be absorbed by the oral mucosa?
Fluoride in toothpaste can be absorbed into sublingual area
What are the different types of oral mucosa?
-Lining
-Masticatory
-Gustatory
Where is each type of oral mucosa in the mouth?
What is masticatory mucosa subject to?
Friction and compression
Where is masticatory mucosa found?
Hard palate, gingiva
What type of epithelia is found in masticatory mucosa?
Parakeratinised
What is the lamina propria in masticatory mucosa like?
Thick, Strong
What comprises the lamina propria and epithelium in masticatory mucosa?
Mucoperiosteum
What is lining mucosa like?
Mobile and distensible
Type of epithelium of lining mucosa?
Non- Keratinised Stratified Squamous
Where is lining mucosa found?
Buccal and Labial Surfaces, ventral surface(bottom) of tongue, floor of mouth and soft palate
How is the lamina propria and submucosa structured in lining mucosa?
-Loose and Vascular lamina propria
-Wide sub-mucosa
What is the turnover of lining mucosa like?
-More rapid turnover than masticatory mucosa
What is gustatory mucosa similar to?
Similar to masticatory as tongue has a role in mastication
What is the epithelium of the gustatory mucosa?
Keratinised Stratified Squamous
Where is gustatory mucosa present?
Only on dorsal of tongue
What is gustatory mucosa characterised by?
Papillae, some bearing tastebuds
