25
Demilunes are crescent shaped structures on the serous
cells of a:
Predominantly mucous salivary gland
26
The intercalated ducts are lined by:
Low cuboidal cells
27
The striated ducts are lined by:
Tall columnar cells
28
The striated duct appears striated because of:
Basal infoldings only; Numerous mitochondria only
29
The pH of secretion of an intercalated duct is:
Isotonic to plasma
30
As compared to plasma the final saliva secreted in the
oral cavity is:
Hypotonic
31
The intercalated & striated ducts are poorly developed
in the:
Sublingual gland
32
The gland which is devoid of a capsule is:
Minor salivary gland
33
The glands of Blandin & Nuhn are located:
Near the apex of the tongue
34
The only minor serous salivary gland is the:
Von Ebner glands
35
The primordium of the parotid and submandibular glands
appears during:
6th week of intrauterine life
36
The primordium of the sublingual gland appears during:
10th week of intrauterine life
37
The minor salivary glands begin their development during:
3rd  month of
intrauterine life
38
The total volume of saliva secreted daily by humans is
approximately:
750 ml. It is in the range of 640 ml to 1200 ml per day.
39
Major bulk of the saliva is produced by:
Submandibular gland
40
The lubricant action in whole mouth saliva is due to its:
Glycoprotein content
41
Taste bud growth and maturation is mediated by:
Gustin
42
The antimicrobial actions in saliva is due to the
Histatin; Lysozyme; Lactoferrin
43
The component in saliva that inhibits calcium phosphate
deposition remineralization of tooth is:
Statherin
44
Comparatively minor salivary glands do not occur in:
Gingiva
45
Excretory duct of parotid glands discharge at:
Opposite to maxillary 2nd molar in buccal mucosa
46
The duct of Submandibular salivary gland is known as:
Wharton’s duct. Duct of parotid gland is Stenson’s duct;
Sublingual gland duct is also known as the Bartholin’s duct.
47
The Submandibular gland duct opens in to the oral cavity
at the:
Carunula sublingualis
48
Pure mucous minor salivary glands are the:
Glossopalatine glands and the palatine minor salivary
glands.
49
The arch that is essential for the proper development of
salivary gland epithelial structures
Ectomesenchyme of First arch
50
Intercalated ducts of salivary glands are lined by:
Short cuboidal cells. Columnar cells line the striated
ducts of salivary glands. The lining of the terminal ducts, nearer to the
striated ducts are tall columnar while those near to the orifice are squamous
type of epithelial cells.
51
Onocytes are associatd with:
Terminal ducts of salivary glands
52
Major concentration of the capillaries in salivary glands
occurs in association with:
Striated duct of salivary glands
53
The salivary gland that is most resistant to atrophic
changes is the:
Sublingual salivary glands
54
Salivary calculi most often occur in the:
Submandibular salivary glands. The reasons for this are
that the duct carries saliva against gravity, the saliva is very mucous and
the path of the duct of this gland is very tortuous.
55
Focal accumulations of the lymphocytes are normally seen
in duct walls of the:
Minor salivary glands. They are associated with
immuno-surveillance of the glands.
