Epithelial Glands II (exam 1)

Question 1

Each lobule is the equivalent to what

Answer 1

A simple, branched gland

Question 2

what is Stroma

Answer 2

The CT that surround the entire gland

Question 3

What are septa (trabeculae)

Answer 3

ar extensions of the capsule into the epithelial components of the gland that divide the gland into subdivisions called lobes and lobules

Question 4

Acini can be what types of glands

Answer 4

Serous, mucous, or mixed (sero-mucous)

Question 5

What covers the outer surface of the acinus

Answer 5

The basement membrane

Question 6

Acini are what

Answer 6

The secretory components of a lobule

Question 7

Lobules are a subdivision of what

Answer 7

The lobe

Question 8

what separates lobules

Answer 8

Delicate septae

Question 9

where can myoepithelial cells be found

Answer 9

between the basement membrane and secretory cells of the acinus

Question 10

what are myoepithelial cells derived from

Answer 10

Epithelium but are characterized by extensive actin bundles resulting in contractility

Question 11

What is the function of myoepithelial cells

Answer 11

help to express the secretions of the acini into the intercalated ducts

Question 12

what are found between the basement membrane and the secretory cells of the acinus

Answer 12

Myoepithelial cells

Question 13

What are intralobular ducts

Answer 13

Ducts that lie within the lobule

two types: intercalated and striated

Question 14

what are the two types of intralobular ducts

Answer 14

Intercalated ducts and striated ducts

Question 15

What is the function of intercalated ducts

Answer 15

drain the secretory acini

involved in bicarbonate/chloride ion exchange

Question 16

What are intercalated ducts lined with

Answer 16

simple squamous epithelium transitioning to low cuboidal epithelium

Question 17

What are striated ducts lined with

Answer 17

Simple cuboidal epithelium transitioning to columnar epithelium with basal striations (for active transport)

Question 18

what is the function of striated ducts

Answer 18

actively reabsorb sodium ions; passively reabsorb chloride ions; actively secrete potassium ions

Question 19

Why are basal striations present in striated ducts

Answer 19

Caused by the presence of mitochondria

Question 20

list the order of the ducts

Answer 20

Acinus (gland part) —-> intercalated ducts (simple squamous-simple cuboidal)—>striated duct (simple cuboidal-to-columnar)—-> interlobular ducts (pseudostratified) —–> intralobar ducts (columnar to stratified columnar) —> Lobar ducts (stratified columnar epithelium)

Question 21

Where are interlobular ducts found

Answer 21

in the septae between adjacent lobules

Question 22

How are interlobular ducts formed

Answer 22

by the confluence of two or more striated ducts

Question 23

What are interlobular ducts lined with

Answer 23

pseudostratified columnar epithelium

Question 24

how are intralobar ducts formed

Answer 24

The confluence of two or more interlobular ducts

Question 25

What are intralobar ducts lined with

Answer 25

Columnar epithelium transitioning into stratified columnar

Question 26

what forms lobar ducts

Answer 26

The confluence of two or more intralobar ducts

Question 27

What are lobar ducts lined with

Answer 27

stratified columnar epithelium

Question 28

List examples of minor salivary glands located throughout the oral cavity

Answer 28

Von Ebner’s glands, labial glands, palatal glands, and buccal glands

Question 29

List the major salivary glands

Answer 29

Parotid, Submandibular, Sublingual
