Labial and Buccal Mucosa line what? |
Inner lips and cheeks |
|
|
How does Labial mucosa and Buccal mucosa appear? |
Opaque Pink Shiny moist compressible tissue that stretches easily Melanin pigmentation may be noted Fordyces spots |
|
|
What are Fordyce Spots? |
are scattered throughout the tissue
normal variant,
visible as small yellowish bumps on the surface of the mucosa corresponding to sebum from misplaced sebaceous glands in the submucosa |
|
|
Histology features of Labial Mucosa |
.......... |
|
|
Buccal and Labial mucosa are what kind of epithelium? |
Nonkeratinized stratified squamous epithelium |
|
|
The nonkeratinized stratified squamous epithelium of the labial and buccal mucosa is what? |
Extremely thick tissue that overlies and obscures a lamina propria with an extensive vascular supply |
|
|
The lamina propria has what? |
irregular blunt connective tissue papillae but contains some elastic fibers and collagen fibers |
|
|
The lamina propria overlies what? |
A Submucosa |
|
|
What does the Submucosa contain? |
Adipose Connective Tissue Minor Salivary glands |
|
|
ALVEOLAR MUCOSA |
.................. |
|
|
The alveolar mucosa appears how? |
reddish- pink tissue with blue vascular areas Shiny Moist |
|
|
This shiny moist region is extremely what? and Lines what? |
Mobile and lines vestibules of the oral cavity
|
|
|
What kind of epithelium is alveolar mucosa? |
Extremely thin, nonkeratinized stratified squamous epithelium that overlies but does not obscure, an extensive vascular supply in the lamina propria |
|
|
Because the extremely thin, nonkeratinized stratified squamous epithelium overlies but does not obsure an extensive vascular supply in the lamina propria is makes the mucosa appear how? |
Redder than the labial and buccal mucosa |
|
|
TRUE OR FALSE?
Connective tissue papilla is sometimes absent, and numerous elastic fibers are present in the lamina propria which allows mobility of the tissue |
TRUE |
|
|
The submucosa contains what? |
Minor salivary glands
numerous elastic fibers in a loose connective tissue |
|
|
The submucosa is attached where? |
to the underlying muscle or bone, increasing the ability of the tissue to move |
|
|
Where is the tissue located? |
between the moving lips and the stationary attached gingiva |
|
|
VENTRAL TONGUE SURFACE AND FLOOR OF THE MOUTH |
.............. |
|
|
How do both the ventral tongue surface and the floor of the mouth appear? |
reddish- pink tissue with vascular blue areas of veins
shiny, moist, compressible |
|
|
The floor of the mouth has some what and the ventral surface of the tongue is what? |
Has some mobility
is firmly attached yet allows some stretching along with the tongue muscles |
|
|
Both the ventral tongue surface and the floor of the mouth have what kind of epithelium? |
Extremely thin nonkeratinized stratified squamous epithelium overlying but not obscuring the lamina propria with an extensive vascular supply |
|
|
What provides the ability to stretch and supply moisture? |
Some elastic fibers and a few minor salivary glands |
|
|
The associated submucosa with the ventral surface of the tongue is what? |
Extremely thin and attached to the underlying tongue muscle |
|
|
The submucosa being attached to the underlying tongue muscle allows what? |
the mucosa and muscles to function as one unit. Reducing mobility during mastication and speech |
|
|
What does the submucosa consist of? and what does it give? |
Loose connective tissue Adipose connective tissue Submandibular salivary glands Sublingual salivary glands
its compressibility and moisture |
|
|
The Submucosa associated with the floor of the mouth is what? |
loosely attached to the underlying bone and muscles, giving the tissue its mobility when the attached tongue moves during mastication and speech |
|
|
The connective tissue of the lamina Propria is what? |
Broad in the floor of the mouth |
|
|
SOFT PALATE |
