Name 4 cellular adaptations
- 1. Hypertrophy
- 2. Hyperplasia
- 3. Atrophy
- 4. Metaplasia
If the limits of adaptive responses are exceeded or if cells are exposed to injurious agents or stress, deprived of essential nutrients, or become compromised by mutations that affect essential cellular constituents, a sequence of events follows that is termed _______?
The end result of cell injury is _____?
What are the two principal pathways of cell death?
Apoptosis and Necrosis
Cellular adapatation which refers to an increase in the size of cells, resulting in an increase in the size of the organ.
Hypertrophy can be physiologic and pathologic. Give examples of both:
- 1. Physiologic hypertrophy:
- a. increase workload
- b. massive increase in size of uterus during pregnancy (hormone induced)
- 2. Pathologic hypertrophy
- a. chronic hemodynamic overload (heart)
is an increase in the number of cells in an organ or tissue, usually resulting in increased mass of the organ or tissue.
