The core of general pathology begins with cellular adaptation and injury. When cells encounter physiological stress or pathological stimuli, they first attempt to adapt through processes such as atrophy, hypertrophy, hyperplasia, or metaplasia. However, if the stress exceeds the cell’s adaptive capacity or if the stimulus is inherently harmful, cell injury occurs. This injury can be reversible, allowing the cell to return to homeostasis, or irreversible, leading to cell death. In veterinary pathology, the two primary pathways of cell death—necrosis and apoptosis—are critical indicators of disease severity and type. Necrosis, often caused by external factors like toxins or ischemia, results in the loss of membrane integrity and subsequent inflammation. In contrast, apoptosis is a programmed, energy-dependent process used to eliminate redundant or damaged cells without triggering an inflammatory response.
