Answer 1

permeability barrier, prevent transport of proteins from lumenal side to basolateral side of the cell

Question 2

Desmosomes

Answer 2

hold together epithelial cells

Question 3

Gap Junctions

Answer 3

allow water-soluble molecules to pass from cytoplasm of one cell to cytoplasm of another cell—allows equilibration within connected epithelial cells

Question 4

Basal Lamina

Answer 4

type of desmosomes, joins epithelial cell to basal side of cell

Question 5

Fibroblasts

Answer 5

secrete collagen, reticulin, and elastin, which are structural proteins

Question 6

Reticulin

Answer 6

thin fiber found in spleen and lymph nodes

Question 7

Elastin

Answer 7

highly cross-linked protein found associated with organs requiring some elasticity (lungs, skin, blood vessels)

Question 8

Collagen

Answer 8

triple-stranded, insoluble, fibrous protein, highly cross-linked

Question 9
