Q

myoepthelial cells of acini have actin and myosin that squeeze the acinus to cause what

A

ejection of saliva

19
Q

What kind of cell:

Pyramidal shape

Resting on basal lamina

Short, irregular microvilli

Exhibit many characteristics of polarized, protein secreting cells

Joined by zona occludens,
desmosomes, gap junctions

A

serous cell

20
Q

What kind of cell?

Cuboidal to columnar

Oval nuclei pressed toward the base

Arranged in tubules around a central lumen

May or may not be accompanied by a serous demilune

A

mucous cell

21
Q

What kind of cell?

Found surrounding the acini but within the basal lamina

Highly branched cells

Also associated with tubules; these are spindle shaped and lie parallel to the length of the duct

A

Myoepithelial cells

22
Q

what order does fluid flow through ducts

A

intercalated ducts –> striated ducts
–> excretory duct –>

23
Q

What kind of duct?

Smallest duct

Several acini drain into intercalated duct

Cuboidal epithelium

Adds specific proteins and water to saliva

Round nucleus that fills most of the cell

A

intercalated

24
Q

What kind of duct?

Longer and more active duct

Site of reabsorption
- Against concentration gradient
- Requires energy (ATP)
- Converts isotonic (primary saliva
to hypotonic fluid (secondary
saliva)

Highly polarized
- short microvilli to increase SA
- numerous infoldings of
basolateral membrane (striations)
- vertically aligned mitochondria

A

striated ducts

25
Q

What kind of duct?

Lacks striations

Series of connecting ducts becoming progressively wider

Moves from single epithelial layer to stratified epithelium

Lumen

Irregularly spaced nuclei

Often in septa; surrounded by fibroblasts

A

Excretory Duct

26
Q

Capillaries provide

A

water

27
Q

fluid from capillaries empties in and cells take it up which produces

A

water

28
Q

primary saliva is formed by what cells

A

secretory

29
Q

secretory cells add/produce _____ to saliva

A

proteins/glycoproteins

30
Q

secretion is regulated by

A

secretory granules/vesicles

31
Q

unstimulated salivary glands are full of

A

zymogen granules

32
Q

plasma cells produce

A

antibodies

33
Q

secretory cells have receptors that will bind to the _______ and pass them into the saliva

A

antibodies

34
Q

primary saliva is produced by _____ and becomes secondary when it goes through ______

A

acini ; ducts

35
Q

primary secretion - acini - h2o ________

A

permeable

36
Q

secondary secretion - duct - h2o __________

A

impermeable

37
Q

secretion in ______ and reabsorption along the ______

A

acini ; ducts

38
Q

ducts modify saliva by changing the amounts of ___ and ____

A

Na+ and K+

39
Q

primary saliva goes from _____ to ______ as it passes through the duct system

A

hypertonic to hypotonic

40
Q

parotid is all _____. glands

A

serous

41
Q

submandibular is mostly ____ with some _____

A

serous ; mucus

42
Q

sublingual is mostly ____ with some _____

A

mucus ; serous

43
Q

von Ebner’s glands are purely _______ and are found only in _______ glands

A

serous ; minor salivary
