What type of secretion is when the product is released into a duct or directly onto an epithelial surface?

Exocrine secretion

1

What is the term for the components that are directly involved with the primary function of a substance?

Parenchyma

2

What are the three ways to classify exocrine glands?

Morphology, method of secretion, product that is secreted

3

What is the term for the components of a substance providing mechanical or metabolic support?

Stroma

4

How are exocrine glands classified by morphology?

Categorized by the shape of the secretory arrangement and the arrangement of the ducts

5

What is the most common method of secretion of exocrine glands?

Merocrine (eccrine)

6

Goblet cell, salivary glands, pancreas, all sweat glands in children, and many adult sweat glands are examples of what type of exocrine glands?

Merocrine (eccrine) glands

7

How do merocrine glands accomplish their method of secretion?

Exocytosis

8

What is a positive feature of exocytosis as a method of secretion of merocrine glands?

No cellular damage

9

Sebaceous glands and the tarsal (Meibomian) glands of eyelids are examples of what type of exocrine gland?

Holocrine

10

What makes up the secretory product of holocrine glands?

Entire cell with intact vacuoles

11

What occurs with the cell itself with holocrine glands?

The cell matures and dies while becoming a part of the secretory product

12

Holocrine glands are specifically associated with what concept?

Odor

13

Lactating mammary glands, some adult sweat glands (pubic and axillary regions), ceruminous glands in external auditory canal, and ciliary "Moll's) glands are examples of what type of exocrine gland?

Apocrine

14

Lactating mammary glands, some adult sweat glands (pubic and axillary regions), ceruminous glands in external auditory canal, and ciliary "Moll's" glands are examples of what type of exocrine gland?

Apocrine

15

What makes up the product of apocrine glands?

Cytoplasm, membrane, and intact vacuoles

16

What types of exocrine glands are associated with odor?

Holocrine and apocrine

17

What is the term for the smallest division of a gland that is a group of cells surrounding a cavity?

Acinus

18

What is a small group of serous cells attached to a mucus acinus?

Serous demilune

19

What are the contractile cells with epithelial origin?

Myoepithelial cells

20

Myoepithelial cells wrap around what structure?

Acini

21

Myoepithelial cells are found where?

Salivary and sweat glands, lacrimal glands, lactating mammary glands

22

What is the function of myoepithelial cells?

To assist secretion

23

What type of exocrine gland produces proteins?

Serous glands

24

What is the shape of the cells of serous glands?

Trapezoid shaped

25

What are examples of serous glands?

Pancreas, parotid gland, chief cells in stomach

26

What is the appearance of the nucleus of serous glands?

Round and noticeable

27

What is the staining characteristic of serous glands?

Tend to pick up stains well

28

Goblet cells, mucous cells in stomach, and the minor salivary glands in tongue and palate are examples of what type of exocrine gland?

Mucus glands

29

How do mucus gland cells typically stain?

Light
