Flashcards in Parotid, submandibular and sublingual glands Deck (35)
1

what are the functions of the salivary glands

•Begin digestion of starches
•Keep mouth moist
•Lubricate food
•(helps) prevent tooth decay
•Controlling bacterial flora of
oral cavity

2

what is serous saliva

amylase, lysozyme, protein secreting

3

what is mucous saliva

contains sialomucins

4

what is the largest salivary gland

parotid

5

what is the parotid sheath

part of deep investing fascia of the neck
capsule that encloses the parotid gland

6

where does the parotid gland enter the mouth

2nd upper molar

7

what is the function of the fatty tissue around the parotid

allows flexibility around the mandible

8

leaves via the internal acoustic meatus and exits via the stylomastoid foramen

facial nerve

9

what two branches of the facial nerve are given off before it enters the parotid gland

posterior auricular and digastric

10

what nerve can be damaged in removal of tumours in the parotid gland

facial

11

what structures are found in the parotid gland

retromandibular vein

external carotid artery

facial nerve

parotid lymph nodes

12

what is the secretomotor aka psymp innervation to the parotid gland

glossopharyngeal

and auriculotemporal branch of V3

13

what is the sympathetic innervation to the parotid gland (causes vasocontriction and reduction in saliva)

superior cervical ganglia on the ECA

14

what is the cutaneous innervation over the parotid gland

auriculotemporal (v3)

great auricular (c2 and 3)

15

where are the submandibular glands

found along the mandible above and below mylohyoid muscle

the gland wraps around mylohyoid

16

what nerve loops around the submandibular glands

lingual

17

what are the relations of the submandibular gland

digastric muscle
facial artery
mylohyoid muscle
hypoglossal nerve

18

where does the submandibular duct open into

base of the frenulum (sublingual papilla)

19

what is the blood supply to the submandibular gland

submental arteries (branch of facial)

20

what is the venous drainage of the submandibular gland

submental veins to lingual and facial veins

21

what gland is mostly mucous secreting

sublingual

22

where is the sublingual gland

floor of the mouth between the mandible and hyoglossus muscle, lateral to the submandibular duct and lingual nerve

sits in the sublingual fossa of the mandible, superior to the anterior part of the mylohyoid line

23

what is the blood supply to the sublingual gland

same as submandibular - sublingual arteries and submental

submental veins to lingual and facial veins

24

what are the relations of the sublingual gland

lingual nerve
submandibular duct
hypoglossal nerve

25

what is the parasympathetic innervation of sublingual and submandibular glands

chorda tympani (cn 7) plus lingual nerve from v3

26

what is the sympathetic innervation to the submand and subling glands

superior cervical ganglia on the eca

27

where in the oral cavity can minor salivary glands be found

buccal
palatine
lingual
labial

28

what is the innervation of minor salivary glands

cn 7 and 5

29

what is a mucocoeles

swelling due to blockage of the associated duct

30

what is mumps

virus
painful swelling over the salivary glands (parotid usually)

31

what is the treatment for mumps

supportive only

may spread > meningitis

32

what is sialolithiasis

salivary calculi

found in ducts- pain, swelling, lack of salivation

usually submandibular

surgical resection

33

what is ptyalism

excess salivation
often prior to vomiting

34

what proportion of salivary gland tumours are benign

80%

35

what is the most common salivary gland tumour

pleomorphic adenoma

painless swelling
numbness/ weakness

resection or parotidectomy
