What are the Histological Changes Induced by Physical Stress?
Histological examination reveals several changes in tissues exposed to physical stress:
1. Hypertrophy: Cells can increase in size to cope with increased mechanical demands. Muscle tissues often exhibit hypertrophy in response to regular exercise. 2. Hyperplasia: This involves an increase in the number of cells, often seen in epithelial tissues subjected to chronic irritation or pressure. 3. Atrophy: Prolonged exposure to mechanical stress can lead to a reduction in cell size and number, commonly seen in immobilized or unused muscles. 4. Fibrosis: Excessive mechanical stress can lead to the formation of fibrous tissue, often seen in chronic inflammation or injury.
