Keratinzed stratrified sqaumous
What type of epithelium is found on all other papillae
Stratified squamous
Von Ebner glands are found with _______ tongue papillae
Vallate
Taste buds are NOT found on which tongue papillae
Filiform
What do the intrinsic tongue muscle do
Change the shape of the tongue
What are the three types of oral mucosa
- Masticatory mucosa
- Lining mucosa
- Specialized mucosa
Where is the masticatory mucosa found
Gingiva, and hard palate
What is the surface epithelium of masticatory mucosa
Keratinized or parakeratinized stratified squamous epithelium
What type of cells in the oral mucosa keep their nuclei
Superficial cells of parakeratinized stratified squamous epithelium
Masticatory epithelium, lamina propia has two parts
Papillary layer- thick loose ct, blood vessels, nerves sensory, meissners corpuscles
Reticular layer- more dense ct
Where is the lining mucosa located
Soft palate, underside of tongue, floor of mouth, cheeks, lips
What is the surface epithelium of lining mucosa
Nonkeratinzed stratified squamous generally
Occasionally, parakeratinized
What is the epithelium on the lips, vermillion border
Keratinized stratified squamous
Which areas are thick of the lining mucosa, keratinized or non keratinized
Nonkeratiinized are THICKER
What is the lamina propia in the lining mucosa
Loose ct with blood vessels and nerves
Not much pigment
