Salivary glands Flashcards
Basked cells are Contractile in :
Action
The cells of serous acinus at EM level show the features of :
Protein synthesis
Striated ducts are called so due to the presence of :
Acidophilic basal striations (basal infoldings)
The main duct of parotid gland opens onto inner surface of cheek opposite to second upper molar & is lined with :
Stratified squamous epithelium
Parotid gland produce 25% of salivary & is a :
Compound tubulo-alveolar exocrine gland
Serous demilune (Crescent of Gianuzzi) is Mixed unit of :
Mucous & Serous cells in mixed glands
Basal mitochondria can be seen in :
Striated ducts of salivary glands
The three pairs of salivary glands that secrete into oral cavity are :
Parotid, Submandibular, Sublingual
Submandibular gland produces 70% of salivary volume & the acini are :
Mixed mucous & serous
Sublingual gland produce 5% of salivary & is :
Mixed mucoserous exocrine gland
The basal part of cytoplasm of striated ducts is acidophilic due to presence of :
Mitochondria
by EM basal infoldings can be seen in :
Striated ducts
Mucous acini at LM level are cuboidal or pyramidal, acidophilic & are usually :
Very pale with foamy appearance
Serous demilunes (Crescent of Gianuzzi) is Mixed & present in :
submandibular gland
Striated ducts are the sites of :
Active transport mechanism
They produce watery secretion rich in proteins that also contain enzymes :
Serous acini
They produce a thick viscid glycoprotein (glycosaminoglycan) mucus :
Mucous acini
