Flashcards in Histology of Salivary Glands Deck (13):
1

3 major salivary glands and what secretes them

parotid-stensens duct
submandibular-whartons duct
sublingual-Bartholin's duct

2

3 characteristics of salivary glands

1. small and numerous
2. several locations
3. produce mucous secretions

3

Characteristics of Von Ebners glands

produce pure serous secretions and surround circumvallate papillae

4

purpose of epithelium

lines the ducts and produces saliva

5

purpose of connective tissue

surrounds epithelium and provides support and protection

6

what are epithelial cells that produce saliva called?

secretory cells

7

what do secretory cells form groups of?

acini

8

2 types of saliva and characteristics

1. mucous cells: generate mucous saliva, and has a cloudy appearing cytoplasm
2. serous cells: generate watery saliva, and has a clear cytoplasm

9

salivary gland organization

1.Acini make up lobules which make up lobes

10

3 types of acini

1. serous
2. mucous
3. mucoserous

11

function of myoepithelial cells

can squeeze it and force saliva out of lumen in salivary gland

12

2 salivary duct systems

1. intercalated duct-attached to each acinus (unstratified cubodial epithelium)
2. striated duct-several intercalated ducts (unstratified columnar epithelium)

13

excretory duct in salivary system

largest diameter found in the septum of the gland
pseudostratified columnar to stratifield cubodial
transition to stratified squamous epithelium closer to the oral cavity entrance
