Question 1

Increase in Cell size

Answer 1

hypertrophy

Question 2

Increase in cell #

Answer 2

hyperplasia

Question 3

Hypertrophy requires

Answer 3

gene activation
protein synth
organelle production

Question 4

Tissues that can only undergo hypertrophy–permanent tissues

Answer 4

Cardiac
sk. mm
Nerves

Question 5

Hyperplasia that does not progress to dysplasia

Answer 5

BPH

Question 6

Decrease in stress –> decrease in organ size

Answer 6

atrophy

Question 7

Ubiquitin proteosome degradation

Answer 7

cytoskeleton marked with ubiquitin and destroyed

cell decreases in size –> atrophy
