Lesson 2.1 - Salivary Glands Flashcards
three main pairs of salivary glands
parotid glands
submandibular glands
sublingual glands
ducts under tongue (from submandibular to sublingual to under the tongue)
Wharton’s ducts
structure of salivary glands
capsule
lobules - secretory cells
3 functions of saliva
digestive
lubrication
protection
parotitis is
inflammation of parotid gland
what does mumps cause
parotitis
what will the sono appearance of parotitis be (4)
bilateral
heterogenous
increased vascularity/hyperaemia
what is secondary to parotitis?
reactive lymph nodes
term for salivary gland infection
sialitis
what does sialitis look like sonographically (3)
diffuse heterogenicity
increased vascularity
chronic calcification
dilation of salivary duct term
sialectasis
inflammation of the parotid gland term
parotitis
a condition resulting from duct obstruction of parotid/submandibular glands assoc with pain and swelling
ptyalectasis
where do most salivary gland stones occur?
submandibular
t/f parotid duct calcli are common
false
what is the most common tumour of the salivary gland
pleomorphic salivary adenoma (mixed benign tumour)
sono appearance of adenomas (2)
posterior enhancement and well circumscribed
what glad do malignant tumours most commonly affect
carcinoma
carcinoma sono appearance (3)
heterogenous
smooth walls
internal vascularity
what is sjogrens disease
an autoimmune disorder affecting the moisture producing exocrine glands (tears and saliva)
what syndrome is sjogrens disease associated with, and what does it present as
sicca syndrome - dryness of eyes/mouth
where might simple cysts may occur?
parotid or submandibular glands
what may cause a simple cyst of the salivary gland to become complicated? (3)
haemorrhage
trauma
infection
where is the kuttner lymph node located
between parotid and submandibular gland
