Day 3 Epithelial Tissue

Question 1

most cancers are what?

Answer 1

epithelial tissue cancers (85%)

CARCINOMAS

Question 2

provide an example for squamous cell cancer?

Answer 2

squamous cell carcinoma

- squamous cell lung cancer

Question 3

provide an example for Glandular cell cancer?

Answer 3

adenocarcinoma

-pancreatic adenocarcinoma

Question 4

provide an example for transitional cell cancer?

Answer 4

Transitional cell cancer

urorethral cell cancer

Question 5

what is a papanicolauo test?

Answer 5

a pap test is a collection and microscopic examination of epithelial cells scraped of apical layer of a tissue

in usual pap test they take non-keratinized stratified squamous cells from cervix

the objective is to detect cancerous chnges in non keratinized stratified squamous epithelium

Question 6

Glandular epithelium:

Exocrine glands do what?

Answer 6

discharge secretions (enzymes mucins) on epithelial surface

Question 7

Glandular epithelium:

what are 4 examples of exocrine glands?

Answer 7

serous glands (salivary amylase, pleural fluid)

mucous glands (mucous in saliva or respiratory tract

mixed glands

other (sebaceous

Can be unicellular or multicellular (sheet or pockets with duct to surface

Question 8

Glandular epithelium:

Endocrine glands do what?

Answer 8

Also know as Ductless

Secrete hormones into extracellular fluid (usually blood) by exocytosis for transport to target area

example is tyroid and adrenal glands

Question 11

what is an example of a simple branched tubular?

Answer 11

gastric glands

mucous glands of esophagus, tongue and duodenum

Question 12

what is an example of a simple alveolar ?

Answer 12

not found in adult; a stage in development of simple branched glands

Answer 15

mammary gland

Question 16

what is an example of a compound tubuloalveolar gland?

Answer 16

salivary glands

glands in respiratory passage

pancreas

Question 17

what are three modes of exocrine gland excretion?

Answer 17

merocrine (secretory vesicles in salivary gland)

apocrine (breakdown and regrowth of mammary gland)

holocrine (in sebaceous gland cell division replace lost cells, cells produce secretion increasing size, cells burst releasing cytoplasmic contents )
