Question 6

What is the cell-matrix junction?

Answer 6

Hemidesmosome

Question 7

Describe tight junctions

Answer 7

Impermeable, like a net between 2 cells,

Question 8

Describe adherens junctions

Answer 8

Like Velcro to prevent separation, encircle the cell, attach on inside of each cell to an adhesion belt

Describe Hemidesmosomes

Answer 12

Anchor cell sheet to underlying connective tissue

What are goblet cells?

Answer 24

Only Produce mucous, exocrine gland, found in upper respiratory system and stomach

Question 25

How do you classify epithelia with more than one layer?

Answer 25

Name it by the apical cell shape

Question 26

Describe glandular epithelia

Answer 26

Produce a secretion

Question 27

Classifications of glandular epithelia

Answer 27

Endocrine and exocrine

Question 28

Describe exocrine glands

Answer 28

Secretes too body surface or into body cavity, from inside cell to outside, has duct attached to secretory unit

Question 29

Describe endocrine glands

Answer 29

Secreting into interstitial fluid into blood stream, doesn't have duct

Question 30

What are cytogenetic glands?

Answer 30

Secrete whole cells, only germline cells
