Answer 1

parotid
submandibular
sublingual

Question 2

where does parotid gland lie

Answer 2

on top of masseter and duct pierces buccinator

Question 3

where does submandibular gland lie

Answer 3

loops around mylohyoid muscle with deep and superficial head

Question 4

what do each of the salivary glands secrete

Answer 4

parotid - serous
submandibular - serous and mucus
sublingual - serous and mucus

Question 5

what are functions of salivary glands

Answer 5

begin digestion of starches
keep mouth moist
lubricate food
help prevent tooth decay
control bacterial flora of oral cavity

Question 6

outline submandibular ducts

Answer 6

approx 5cm long and begin between mylohyoid and hyoglossus
lingual nerve CN V3 loops under duct before it opens into oral cavity
opens into 3 orifices in the oral cavity besides the base of frenulum (sublingual papilla/ caruncles)
blood supply is via submental arteries (branch of facial artery)
venous drainage is via submental veins (to lingual and facial veins)

Question 7

where does sublingual gland lie

Answer 7

in floor of mouth between mandible and hyoglossus lateral to submandibular duct and lingual nerve CN V3. sits in sublingual fossa of mandible. sublingual folds overly the gland smallest of major salivary glands

Question 8

outline sublingual ducts

Answer 8

numerous ducts and drain into oral cavity via openings into crest of sublingual fold
blood supply is via submental and sublingual arteries (branch of facial and lingual arteries)
venous drainage is via submental veins (to lingual and facial veins)

Question 9

parasympathetic innervation of sublingual and submandibular glands

Answer 9

chorda tympani CN VII & lingual nerve CN V3 > submandibular ganglion > either lingual nerve CN V3 or directly to sublingual and submandibular not in a nerve

Question 10

where are the minor salivary glands found

Answer 10

buccal
palatine
lingual
labial

Question 11

what is mucoleles

Answer 11

swelling due to blockage of associated ducts

Question 12

what innervates minor salivary glands

Answer 12

CN VII and CN V

Question 13

what provides parasympathetic innervation to buccal and palatine minor salivary glands

Answer 13

greater petrosal CN VII

Question 14

what provides parasympathetic innervation to lingual and labial minor salivary glands

Answer 14

chorda tympani of CN VII

Question 15

what is mumps

Answer 15

painful swellings over salivary glands; most commonly parotid glands

Question 16

what are salivary stones

Answer 16

pain, swelling and lack of salivation common in submandibular duct due to upwards course into oral cavity
