Study Notes
Cellular Response to Stress and Adaptive Potential
- The content and learning objectives focus on the cellular response to stress and the characteristics of adaptive responses.
- Cells maintain homeostasis and can undergo adaptation or injury when exposed to stimuli.
- Adaptive responses include hypertrophy, hyperplasia, atrophy, and metaplasia, each with distinct characteristics and examples.
- Different cell types have varying mitotic activity and adaptive potential, classified as labile, stable, or permanent cells.
- Hypertrophy involves an increase in cell size, while hyperplasia involves an increase in cell number, occurring in different cell types.
- Physiologic hypertrophy can result from increased mechanical demand, such as in skeletal muscles of athletes or the myocardium during pregnancy.
- Pathologic hypertrophy occurs due to increased mechanical demand from pathological processes, like in the myocardium during hypertension.
- Mechanisms of mechanical-demand-induced hypertrophy involve the activation of transcription factors and signaling pathways.
- Physiologic hyperplasia can be hormone-induced, like in the female breast during pregnancy, while pathologic hyperplasia can result from excessive hormonal stimulation or viral infections.
- Atrophy involves a decrease in cell size or number and occurs in response to decreased protein synthesis, increased degradation, or chronic ischemia.
- Examples of atrophy include embryonic structures during fetal development, myometrium after delivery, and organ atrophy due to chronic ischemia or metabolic abnormalities.
- Overall, the content provides a detailed understanding of the cellular response to stress and the various adaptive responses in different cell types.
