Salivary Gland Development and Structure (CF 20-21)
Preguntas del test (12)
1Salivary gland development begins between the 9th and 10th week of development. The lumen of salivary glands are formed via apoptosis.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
2Salivary glands respond to acetylcholine for both sympathetic and parasympathetic stimulation. The parasympathetic secretion is proteins and sympathetic secretions are water and ions.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
3The salivary glands are controlled by post-ganglionic nerve fibers from the inferior salivary nucleus. The nerves and blood vessels are within the septum formed by the connective tissues.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
4Serous acini cells have secretory vesicles whereas mucous acini have secretory granules. Minor salivary glands of the palate have mucous secretions and minor salivary glands from the back of the tongue have serous secretions.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
5The circadian rhythm is important because minor salivary glands are active at night. Reduction in salivary secretions with an increase in ductal volume with age is typical.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
6The secretions of the parotid gland are exclusively serous and both its striated and intercalated ducts are long. The secretions of the sublingual gland are exclusively mucous and both its striated and intercalated ducts are short.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
7The submandibular gland is the largest major salivary gland and it produces the majority of salivary secretions. Salivary glands in general are compound acinar in shape and engage in merocrine secretion.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
8Which order is correct order of duct types starting from the acinus?
- Astriated, intercalated, excretory
- Bexcretory, striated, intercalated
- Cintercalated, excretory, striated
- Dintercalated, striated, excretory
- Estriated, excretory, intercalated
9Serous demilunes are made of serous cells at the center with mucous cells on their distal ends and this formation can only be seen in conventional fixation. These serous demilunes can be found at the submandibular gland.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
10Which of the following is correct?
- AThe excretory duct of the parotid is Wharton's duct
- BThe excretory duct of the sublingual gland is Stensen's duct
- CExcretory ducts are made from columnar cells
- DIntercalated ducts are cuboidal cells.
- EStriated ducts are made from pseudostratified epithelium
11The parotid gland's blood supply is the external carotid artery. Its secretions are only serous and is has the highest frequency for salivary gland tumors but they are usually benign.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
12The most common cause of sialadenitis is mumps. It can also be caused by HIV, herpes, tuberculosis, and infection by staph pyogenes or staph aureus, diabetes, adrenal disease, and various metabolic conditions.
- ABoth true
- BFirst true, second false
- CFirst false, second true
- DBoth false
