Study Notes
Cellular Adaptation and Atrophy
- Cellular adaptation is a response to adverse environmental changes, allowing cells to survive and maintain homeostasis.
Types of Cellular Changes
- Physiologic atrophy: an example is the decrease in uterus size after pregnancy, a reversible and adaptive response to changes in hormonal environment.
Dysplasia
- Associated with pathologic adaptation, which is a cellular abnormality and not considered adaptive.
Cellular Atrophy
- A decrease in cell size, which can be physiologic (reversible) or pathologic (irreversible).
- If enough cells in an organ undergo atrophy, the organ's function may be impaired.
Organ-Level Consequences of Atrophy
- The result of cellular atrophy on an entire organ can lead to impaired organ function.
Hypertrophy
- A morphological adaptation observed as an increase in cell size, often in response to increased workload or demand.
Assessment of Morphological Adaptations
- Morphological adaptations are usually assessed at the tissue or organ level, outside of specialized branches of biomedicine.
