- alveolar mucosa
- floor of the mouth
- ventral surface of the tongue
- soft palate
what are four clinical considerations for lining mucosa?
- sutures needed-softer tissue
- fordyce spots
- easier to inject
- infections spread quickly-nonkeratinized
what are three types of mucosa?
- lining mucosa
- masticatory mucosa
- specialized mucosa
what are the three locations of masticatory mucosa?

masticatory mucosa is _____ and _____
rubbery and resilient
masticatory mucosa can either be ________ or _______
orthokeratinized or parakeratinized
what is the least common type of keratin?

what color is orthokeratinized mucosa?
t/f orthokeratinized mucosa has nuclei
FALSE- no nuclei
t/f parakeratinized tissue is red
what type ortho or para is associated with higher levels of attached gingiva?
which type ortho or para has special protection against bacterial invasion, mechanical irritation and dryness?
orthokeratinized tissue is _____ in color has ____ nuclei and is the _____ common in the oral cavity. It protects against ______, ______ and ______ attack. Also protects against ______ and ____ ____.
- heat loss
parakeratinized is ____ in color it _____ have nuclei and is associated with higher level of ______ _____. It has special protection against _______ invasion, ______ irritation and ______
- attached gingva
what are three clinical considerations of masticatory mucosa?

4-11 vertical ridges
where is the taste bud located on the foliate?
how many circumvallate papilla are there?
what papilla are the von ebner's associated with and what is their purpose?
- to rinse circumvallate in order to taste
what is an example of nonkeratinzed going to keratinized?

what is hyperkeratinized in response to?
what is an example of chemical trauma causing hyperkeratinized mucosa?
heat from smokin and hot fluids
t/f hyperkeratinized mucosa is reversible if trauma is taken away?
what is the purpose of tissue grafting?
to reduce gingival recession and increase the amount of attached keratinized tissue
