Cell Adaptations Flashcards
1
Q
cells adapt to:
A
- adverse conditions (ex. injury)
- altered workload
2
Q
atrophy
A
- decrease in cell size and/or number of cells
- decrease tissue mass & lvl of Fx
3
Q
hyperplasia
A
- increase in number of cells & level of Fx
- increase tissue mass
4
Q
types of hyperplasia
A
- compensatory (beneficial)
- pathologic (associated w/ disease)
5
Q
hypertrophy
A
- increase in cell size & level of Fx
6
Q
metaplasia
A
1 normal cell/tissue type replaces another normal cell/tissue type (replacement type not normal for site)
7
Q
cause of metaplasia
A
chronic irritation & inflammation
8
Q
dysplasia
A
abn cells in a tissue
9
Q
anaplasia
A
undifferentiated cells
10
