AYURVEDA LIBRARY ONLINE CLASSES VARANASI. Pathology Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues (biopsy samples), bodily fluids, and in some cases the whole body (autopsy). ❖ Terms for Cell Adaptation Hypertrophy - Increase in the size of cells. Atrophy -decrease in the size of an organ. Hyperplasia - Increase in the number of cells. Aplasia - failure of cell production. Hypoplasia- decrease in the number of cells. Metaplasia - replacement of one differentiated cell type by another type of cell (does not cause cancer). Dysplasia - abnormal cell growth (abnormal histology or anatomical structure) (may cause cancer or may be not) Cardinal signs of inflammation - 5 classical features of inflammation were described by-celsus.
