submandibular-whartons duct
sublingual-Bartholin’s duct

Question 2

3 characteristics of salivary glands

Answer 2

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

Question 3

Characteristics of Von Ebners glands

Answer 3

produce pure serous secretions and surround circumvallate papillae

Question 4

purpose of epithelium

Answer 4

lines the ducts and produces saliva

Question 5

purpose of connective tissue

Answer 5

surrounds epithelium and provides support and protection

Question 6

what are epithelial cells that produce saliva called?

Answer 6

secretory cells

Question 7

what do secretory cells form groups of?

Answer 7

acini

Question 8

2 types of saliva and characteristics

Answer 8

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

Question 9

salivary gland organization

Answer 9

1.Acini make up lobules which make up lobes

Question 10

3 types of acini

Answer 10

1. serous
2. mucous
3. mucoserous

Question 11

function of myoepithelial cells

Answer 11

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

Question 12

2 salivary duct systems

Answer 12

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

Question 13

excretory duct in salivary system

Answer 13

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
