Study Notes

Cellular Adaptations

Morphological adaptation observed at the cellular level: Hypertrophy (an increase in cell size)
Cellular adaptation in cell biology and pathophysiology: A response to changes in the environment, allowing cells to maintain homeostasis and survive

Physiologic and Pathologic Adaptations

Physiologic adaptations: Reversible changes that help cells cope with stress, returning to normal once the stress is removed (e.g., muscle hypertrophy in response to exercise)
Pathologic adaptations: Permanent changes that result in cell damage or disease (e.g., cancer)

Dysplasia and Atrophy

Dysplasia: A cellular adaptation characterized by abnormal cell growth, often leading to cancer
Physiologic atrophy: A decrease in cell size or number in response to a decrease in demand or disuse (e.g., atrophy of muscles in astronauts after prolonged space travel)
