    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
