Oral Mucosa Flashcards
What are the functions of the oral mucosa
Protection
Sensation
Secretion
Thermal regulation
What are the three types oral muscles according. To function
Masticatory mucosa - keratinised, contact with food
Lining mucosa - cover floor of mouth, non keratinised
Specialised mucosa - covers dorsal tongue and papillae
What is the separation of the oral mucosa and skin
Vermillion border of lips
What are the factors affecting the colour of the mucosa
Conc and state of dilation of blood vessels in underlying ct
Thickness of epi
Degree of keratinised
Amount of melanin pigmentation
How is oral mucosa diff from skin
Color Moist surface A sense of skin appendages Minor salivary glands Texture surface Firmness
What are fordyces spots
Pale yellow spots
Normal variation
Lips, buccal mucosa, alveolar mucosa, tonsilar pillar
What su the structure of the oral mucosa
Overlying oral epi
Underlying ct
Interface between epi and ct is compromised of a structurless layer called basement mem
Interface irregular have rete ridges
What is oral mucoperiosteum
In elastic attachment firm to vine palate
What is the connective tissue in the oral cav
Salivary glands
Sebaceous glands
Lymphoid tissue
What is a progenitor pop
Divide and provide new cells
What is a maturing pop
Undergo diff maturation
What are the types of oral epi
Orthokeratinised stratified squamous epi
Parakeratinised stratified squamous epi
No keratinised stratified squamous epi
What are the components of lining mucosa
Stratum basale
Stratum spinosum
Stratum superficiale
What su free gingiva
Keratinised
Not Stippled free gingival groove
What is attached gingivae
Keratinised
Stippled
Sep from alveolar mucosa by mucohingival junction
