What Are the Histological Changes Observed in Injured Tissues?
Histological examination of injured tissues can reveal various changes, including cell necrosis, apoptosis, inflammatory infiltrates, and fibrosis. Necrosis is characterized by cell swelling, membrane rupture, and inflammation. Apoptosis, on the other hand, is a controlled form of cell death that does not elicit an inflammatory response. Inflammatory infiltrates, composed of immune cells, can be observed in areas of acute or chronic inflammation. Fibrosis, or scar tissue formation, can occur during the healing process, often resulting in altered tissue architecture.
