Flashcards in Secretion Of Slaiva Deck (26):
1

What kind of secretion form the parotid

Serous

2

What kind of secretion form the submandibular

Mixed mucous and serous

3

What is a mucous secretion and serous

Serous is watery
Mucous is viscous thick with more glycoproteins

4

What secretion is the sublingual

Mostly mucous

5

What happens to the saliva as it travels along the duct

Ions such as sodium and chloride reabs
And pottasium is sec into saliva

6

What is resting secretion

Present throughout the day and night
Keeps mouth and oropharynx
Moist
Lubrictaed
Protected

7

What is stimulated secretion

During eating
Massive increase over short peirod
Sensory stimulated
Gustatory receps on tongue
Mevhanoreceps
Olfactory receps smell
Nociceptors
Higher centres

8

What is whole mouth saliva

Mixed secretions form all glands
All Producing variable volumes
Plus debris and other oral fluids such as gingival crevicular fluid

9

What is the stim and unstim Bol form each of the glands

Unstim
-parotid --> 20%
-submandibular --> 65%
-sublingual --> 7-8%
-minor --> 7-8%


Stim
-parotid --> 50%
-submand --> 30%
-Subling--> 10%
-minor --> 10%

10

What are some inorganic components of saliva

Sodium
Pottasium
Chlorine
Fluoride
Calcium
Phosphate
Bicarbonate

11

What does fluoride in the mouth do

Enamel protection

12

What does calcium do in the mouth

Supersaturated saliva

13

What does bicarbonate do in the mouth

Buffer

14

What are some organic components of saliva

Lipase - fat metab
Hi statins - anti fungal
Immunoglobulins
Growth factors
Amylase - carb metab

15

What are some functions of saliva

Protect tissue
Protect teeth
Enhance taste
Lubriacte food
Neut organic acids
Discourage bac growth
Recycle fluoride

16

Which glands produce amylase and what does it do

Parotid and submand
Hydrolyses carbs to maltose etc
Denatured in stomach
Cleanse mouth

17

What glands prod lipase and what does it do

Lingual glands associciated with circumvaklate papillae
Fat digestion
Resist stomach acid
Babies
Taste buds

18

What is salivary sec dept on

Reflex activity which is innate
Automatic
To a known stimulus such as feeding

19

What are some stumuli that cause salivary sec

Gustatory
Masticatory
Olfactory
Psychic
Visual
Thermo receptive
Possibly nociceptive

20

What instrument is used to sample saliva

Lash let cup and cannula

21

What is the gustatory salivary Reflex

Stumuli delivered to gustatory receptors in taste buds
Basic tastes cause salivary sec
Sour>salt> bitter and sweet

22

What is the role of intra oral ,evhanoreceptors

Output of saliva directly proportional to masticatory forces
Contribute to masticatory reflex

23

Does a true olfactory parotid salivary reflex exist in humans

No

24

What su psychic stimuli

Anticipation of food 'mouthwatering"not proven
May just be awareness of saliva in mouth
Myoepthelial cells or facial musculature

25

What is a conditioned reflex

Demo by Pavlov dog that certain set conditions accompany natural stimulus
Not easily demo in man

26

What are the three pairs of salivary glands major

Parotid
Submandibular
Sublingual

(Numerous minor - lips, cheeks, palate, tongue etc)
