Flashcards in Salivary Glands Deck (30):
1

Where is the parotid gland

Parotid region
Superiorly - zygomatic arch
Inferiorly - info border mandible
Posteriorly - external ear and scm
Bilaterally

2

What is the rough structure of the parotid gland

Lobular
Irregular
Superficial and deep

3

What kind of saliva does the parotid gland produce

Serous saliva

4

How does the parotid gland secretion reach the mouth

Via parotid duct which enters the mouth at upper 2nd molar

5

What are the three anatomical relationships the parotid gland has

Facial nerve
Eca
Retromandibular nerve

6

What does the facial nerve do in the parotid gland

CN 7
Between the superficial and deep fascia in a lame where it divides to its 5 terminal branches

7

What a re the 5 terminal branches of the facial nerve

Zygomatic
Temporal
Buccal
Mandibular
Cervical

8

What makes up the retromandibular Vein

The superficial temporal vein and the the maxillary vein

9

What supplies the parotid gland arterial supply and drains it

Arterial supply - posterior auricular and superficial temporal arteries
Drained by retromandibular vein

10

What si the innervation of the parotid gland

Sensory - auriculotemporal nerve v3
Autonomic - Glossopharyngeal at otic ganglion (+) auriculotemporal
Symp - sup cervical ganglion

11

Where is the sublingual gland found

The floor of the mouth
Sublingual fossa

12

Where does the sublingual secretion drain from in the mouth

Sublingual papillae

13

What si the sublingual gland supplied by in terms of blood

Sublingual and submental arteries from Lingual and facial artery
Corresponding veins drain

14

What si the innervation of the sublingual gland

Similar to submandibular gland

15

What kind of secretion from the sublingual gland

Mucous

16

What kind of secretion form the submandibular gland

Mixed

17

Where is the submandibular gland found

In the submandibular triangle
Superiorly - inf body of mandible,
Anteriorly - abd
Posteriorly - PBD

18

Where does the submandibular secretion come from in the mouth

Form the submandibular duct which terminates I sublingual papilla

19

What is the arterial supply of the submandibular gland

Submental arteries and corresponding veins for draining

20

What si the innervation of the submandibular gland

Parasymp - sup salivary nucleus through chorda tympani and lingual which gives secretomotor
Symp - duo cervical ganglion

21

How does the saliva get modified by salivary ducts

Sodium and chloride taken out of secretion whilst pottasium is pumped in

22

What are some function of saliva

Protection of teeth
Integrity of teeth
Buffer
Initial digestion carbs
Lubrication
Taste
Antibacterial

23

What are some components of saliva

Organic and inorganic
Mucins
Hi statins
IgA
Amylase
Bicrabondat
Pottasium
Calcium
Phosphate

24

What are salivary glands made up of

Sec acini

25

What are the types of secretions

Mucous
Serous
Mixed

26

In mixed acini what is shown

Serous demilune

27

What doe the secretory units converge to form

Intercalated duct simple low cuboidal epi with myoepthelial cells

28

What comes after the intercalated ducts

Striated ducts where makes hypotonic solution then lead to excretory ducts

29

Do mucous acini stain darker or lighter than serous

Lighter than serous

30

What are the three major salivary glands

Parotid
Submandibular
Sublingual
