Study Notes
Adaptive Cellular Responses
- Atrophy: decrease in cell size as an adaptation to stress
- Hyperplasia: increase in the number of cells as an adaptive response
- Hypertrophy: increase in cell size in response to stress
- Metaplasia: change in the pathway of phenotypic differentiation of cells as an adaptive response
Types of Atrophy
- Pressure atrophy: associated with prolonged pressure from benign tumors or cysts
- Disuse atrophy: associated with interruption in nerve supply leading to wasting of muscles
- Ischemic atrophy: linked to the gradual diminution of blood supply due to atherosclerosis
- Cachexia: characterized by general weakness, emaciation, and anaemia, seen in cancer and severely ill patients
- Hypothyroidism: can cause atrophy of the skin and its adnexal structures
