UKCD Histo Oral Glan

test objective answers for oral glands

What are the 2 major groups of minor salivary glands? Seromucous and purely mucous minor salivary glands.
Name the seromucous glands? labial, anterior lingual, buccal and sublingual glands
Name the purely mucous glands? palatine, glossopalatine and posterior lingual glands
What is the structural/functional unit of the salivary gland? a secretory acinus
What are the two major types of secrectoy cells found in these glands? Mucous and serous secretory acinar cells.
How do serous glands appear? large spherical nucleus, apical zymogen granules, and acidophilic (pink) staining cytoplasm
How do Mucous glands appear? flattened basally-located nucleus and an overall lack of cytoplasmic staining due to the loss of the mucous granules during fixation/staining
How is a seromucous acinus structured? The mucous cells have direct access to the lumen of the acinus and the serous cells form a demilune that caps the posterior region of the mucous acinus.
How does the serous secrection reach the acinar lumen? Serouse fluids from the demilune access the lumen of the mucous acinus by an intercellular canal between the mucous cells.
What is a myoepithelial cell? A cell of epithelial origin that has gained the function of contractility. It has the morphological appearance of an octopus, the arms of which surround the acinar cells.
Where are myoepithelial cell types located? Myoepithelial cells are located between the acinbar cells and their basement membrane.
What is the function of a myoepithelial cell? To assist in secretion of acinar contents by gently squeezing the cells of the acinus.
Which divisions of the duct system or a parotid gland are not found embedded in connective tissue? Intercalated and intralobular (secretory/striated) ducts lack demonstrable CT around their outer regions.
What does the lack of connective tissue surrounding a duct facilitate? The ability of the epithelial cells of the duct to effectively exchange content between the lumen and the surrounding capillaries (i.e. secretory activities).
In which division of the duct system do you begin to find significant amounts of CT around the ducts? Interlobular and upward.
What is the function of an intercalated duct? To drain each individual acinus.
Why does a striated duct have this appearance? The basal membrane exhibits infoldings between which are located mitochondria giving the overall appearance of being striated.
What occurs in a striated duct? Water and electrolytes are actively exchanged between the duct lumen and the surrounding capillaries across the basement membrane of the duct epithelial cell.
Name the three major salivary glands. Parotid, submandibular and sublingual glands.
Where does the duct of parotid gland terminate? opens by the second upper molar
Where does the duct of the submandibular gland terminate? on floor of mouth at the submandibular papilla
Where does the duct of the sublingual gland terminate? onto the floor of the mouth via 15-20 ducts along the sublingual fold
What type of secretion is released by parotid glands? purely serous
What type of secretion is released by submandibular glands? primarily serous
What type of secretion is released by sublingual glands? primarily mucous
In which glands would you find serous demilunes? Submandibular and sublingual glands.
List the three tonsillar lymphoid tissues? Palatine, pharyngeal and lingual.
Where is Palatine tonsil located? in the palatine fossa on either side of the oral cavity between the glossopalatal and glossopharyngeal folds
Where is Pharyngeal tonsil located? in the posterior wall of the nasopharynx
Where is lingual tonsil located? comprising the posterior 1/3 of the dorsum of the tongue.
Which tonsils exhibit crypts? The palatine and lingual tonsils have crypts.
Which tonsil is most frequently removed surgically and why? The palatine tonsils. They have secondary (branched) crypts which are not flushed so material can accumulate, rot and cause infections.
What are secondary crypts? Crypts that branch
Which tonsils exhibit secondary crypts? Palatine tonsil
