Ducts of salivary glands, small areas of the pharynx, epiglottis, anus, mammary glands, and urethra

Question 9

What are functions of simple squamous epithelium?

Reduce friction, control permeability, perform absorption and secretion

Question 10

Answer 13

Protection, secretion, and absorption

Question 14

What are functions of stratified columnar epithelium?

Answer 14

Protection

Question 15

Serous glands

Answer 15

Secrete a watery solution that usually contains enzymes, such as salivary amylase in saliva

Question 16

Mucous gland

Answer 16

Exocrine gland that secretes mucins which absorb water to form slippery mucus, such as those in saliva

Question 17

Mixed exocrine glands

Answer 17

Contain more than one type of gland cell and may produce two different exocrine secretions (could be serous or mucous)

Question 18

How endocrine glands release their secretions?

Answer 18

Exocytosis from the gland cells into the fluid surrounding the cell

Question 19

Unicellular glands

Answer 19

Individual secretory cells that secrete mucins. There are two types goblet and mucous cells

Question 20

Where are mucous cells found and where are they?

Answer 20

Unicellular gland cells that are found in pseudostratified ciliated epithelia.

Question 21

Where are goblet cells and what are they?

Answer 21

Unicellular gland cells. They are scattered among simple columnar epithelium of the small and large intestine

Question 22

Secretory sheet

Answer 22

Simplest multicellular exocrine gland. Glandular cells dominate the epithelium and release their secretions into an inner compartment

Question 23

What is an example of a secretory sheet?

Answer 23

Mucus secreting cells in the stomach

Question 24

What’s an example of a simple tubular gland

Answer 24

Intestinal glands. Multicellular

Question 25

What is an example of simple coiled tubular gland?

Answer 25

Merocrine sweat glands

Question 26

What are examples of simple branched tubular glands?

Answer 26

Gastric glands, mucous glands of esophagus, tongue, and duodenum

Question 27

What is an example of a simple alveolar gland?

Answer 27

Not found in adults but is a stage in development of simple branched glands

Question 28

What is an example of a simple branched alveolar gland?

Answer 28

Sebaceous glands

Question 29

What is an example of a compound tubular gland?

Answer 29

Mucous glands (in oral cavity), bulbo-urethral glands (male reproductive system), testes (seminiferous tubules)

Question 30

What is an example of a compound alveolar gland?

Answer 30

Mammary glands

Question 31

What is an example of compound tubuloalveolar gland?

Answer 31

Salivary glands, glands of respiratory passages, pancreas

Question 32

Merocrine secretion

Answer 32

Method of glandular epithelial cell secretion. Exocytosis puts products onto surface of the cell. Ex: serous cells of salivary glands

Question 33

Apocrine secretion

Answer 33

Method of glandular epithelial cell secretion in which the cytoplasm is shed. Ex: Lactiferous cells of the mammary gland

Question 34

Holocrine secretion

Answer 34

Type of glandular epithelial cell secretion. Destroys gland cell by build up of secretory product (ex: sebaceous gland cells)

Question 35

What structures does simple squamous epithelia form?

Answer 35

Alveoli of the lung, inner lining of the cornea of the eye, mesothelial lining of ventral body cavities, and endothelial lining of blood vessels
