Flashcards in C20 Tissues and Cancer Deck (19):
1

Tissues are composed of ? plus ?

cells plus extracellular matrix

2

plant cells surround selves with ECM of ? made of ?

cell wall, cellulose

3

controls orientation of plant growth

deposition of cellulose

4

fibroblasts

type of cell that synthesizes the extracellular matrix and collagen, the structural framework (stroma) for animal tissues, and plays a critical role in wound healing

5

animals ECM tensile strength provided by ?

collagen

6

link extracellular matrix proteins to intracellular cytoskeleton

integrins

7

act as space fillers and resist compression

proteoglycans

8

proteoglycans formed from ? linked to proteins

GAGs (glycosaminoglycans)

9

line all internal and external surfaces of animal body

epithelial sheets

10

? proteins span epithelial cell membranes and attach to similar ones in other epithelial cells

cadherins

11

adherins junction

cadherins linked intracellularly to actin filaments

12

desmosome junction

cadherins linked to keratin filaments

13

tight junctions

seals neighboring cells together to prevent leakage

14

hemidesmosome junction

anchors intermediate filaments to basal lamina

15

gap junction

create small pores that connect cells

16

? in plant cells are similar to gap junctions

plasmodesmata

17

G-protein in mitogen activated signaling

Ras

18

chronic myeloid leukemia is often the result of a specific chromosome translocation that increases activity of ?

abl

19

sonic hedgehog

provides positional information
