How your body adapts: the science of hyperplasia and cell growth
In short: Understand how your cells react to stress and stimuli. This lecture explores the mechanisms of hyperplasia, hypertrophy, and atrophy, explaining how tissue changes to survive or respond to internal and external demands.
The video categorizes cell adaptations into distinct types, including hyperplasia, hypertrophy, metaplasia, and neoplasia. It distinguishes between physiological growth—which occurs as a normal response to bodily needs—and pathological growth, which results from disease or injury.
Key concepts covered include various forms of atrophy, such as disuse, denervation, vascular, ischemic, hormonal, and pressure atrophy. The lecture also touches on preneoplastic and carcinogenic processes, providing a comprehensive overview of how tissues remodel under conditions like starvation, chronic disease, or multi-organ failure.
