exam 2 Flashcards
glandular tissue types
lacrimal
salivary
thyroid
parathyroid
thymus glands
gland definiton
structure that produces a chemical secretion necessary for normal body functioning
exocrine gland
gland that has a duct associated with it, duct is a passageway that always the secretion to be emptied where it needs to be
non-hormone secretion
endocrine gland
ductless gland
hormone secretion
lacrimal glands
paired almond-shaped exocrine glands that secrete lacrimal fluid or tears
what are the major salivary glands
parotid
submandibular
sublingual
parotid salivary gland
largest major salivary gland
serous secretion
25% volume, 2nd most
what is the duct associated with the parotid salivary gland
stensen duct
what contagious viral infection, that affects the parotid gland, usually involves inflammation giving the characteristic of “chipmunk” cheeks
mumps
what can happen if you pierce that parotid gland
facial paralysis
submandibular salivary gland
second largest major salivary gland
serous & mucous secretions
60-65% volume, largest production
where is the submandibular gland located
posterior to the sublingual gland
what is the duct associated with the submandibular gland
wharton duct
sublingual salivary gland
smallest major salivary gland
mucous secretion
10% volume
what is the duct associated with the sublingual salivary gland
bartholin duct
minor salivary gland
<10% volume
scattered throughout the oral cavity
von Ebner salivary glands
base of the large circumvallate lingual papillae on the posterior part of the tongue’s dorsal surface
salivary stones - sialolith
these can form due to blockage of saliva from draining from the duct
ranula
major glands
mucocele
minor glands
hyposalivation
reduced production os saliva
medications, disease, or destruction of salivary tissue can cause this
xerostomia
dry mouth
can result in trauma to unprotected oral mucosa
cervical caries
a frequent complication of dry mouth
sjogren syndrome
systemic autoimmune disease which destroys the exocrine glands that produce both saliva and tears and dries everything out
nicotinic stomatitis
hard palate is whitened by hyperkeratinization caused by heat from tobacco use or hot liquid consumption
thyroid gland
largest endocrine gland
produces and secrete thyroxine
what is the enlargement of the thyroid gland
goiter
parathyroid gland
four small endocrine glands, two on each side
produce and secrete parathyroid hormone
CANNOT PALPATE THESE
thymus gland
endocrine gland, ductless
makes and trains T-cells
