salivary glands Flashcards
salivary gland structure
segements of salivary ducy
intercalated, striated, excretory (in order)
major salivary glands
parotid
subman
subling
locations of minor glands
Palate
Buccal mucosa
Tongue
Floor of mouth
Labial mucosa
Retromolar pad
Oropharynyx
parotid H/E app?
purely serous acini= eosinophilic
which gland
parotid
what granules are present in serous acini
zymogen
acini of subman
mixed gland, mainly serous
what stain can we use to deomstrate mucus acini
mucicarmine
which gland
subman
acini of sublingual gland
mucoserous, mainly mucus
which gland
sublingual
DISTRIBUTION OF MINOR SALIVARY GLANDS
Palate 60%
Tongue 10%
Lips 10%
Cheeks 10%
Retromolar 10%
what is happening
salivation of minor glands
minor glands of the tongue
Glands of Von Ebner
Glands of Blandin and Nuhn
Glands of Weber
Glands of Von Ebner
Circumvalate papillae –
serous
Glands of Blandin and Nuhn
Anterior ventral – mucous
Glands of Weber
Posterior lateral border at foliate papilla -
mucous
MUCOUS EXTRAVASATION REACTION OF SALIVARY GLANDS
due to disruption of the duct system (often from trauma), leads to a mucocele
app of mucocele
swelling, sometimes bluish
mucus extravasation rxn histo (mucocele)
would see enlarged ducts with granulation tissue surrounding mucus with inflammatory cells in it
what is this
mucocele
mucocele of the palate
often superfifical and pop, often multiple present
would need a biopsy to confirm
Ranula
mucocele of the subman gland
ranula
plunging ranula
occurs if ranula goes beneath the mylohyoid: mucin dissects thru the mm
will present as a neck mass
sialolith
salivary stone
trapped saliva will calcify and obstruct the duct
common location sialoliths and why
whartons duct due to the many turns
indications of sialoliths
swelling near glands around meal time
may be painful due to infection
sialoliths with palpation
hard
sialoliths at stensons duct may present with?
pus
what can we use to locate sialoliths
occ radiogrpahs
tx of sialoliths
excision
histo app of sialoliths
calcifed tissue
necrotizing sialometaplasia
unknown cause, reactive condition
can present with swelling and ulceration that can be bilateral or unilateral
