A dynamic and rapidly evolving field, Pathology is the study of disease, or more generally, the study of the biological response to adverse conditions. As an intellectual discipline, Pathology bridges basic and clinical sciences. Basic research into the causes and mechanisms of disease (experimental pathology) goes hand in glove with identifying the morphologic and biochemical manifestations of disease in human patients (anatomic and clinical pathology, respectively). All of these have important diagnostic and therapeutic implications for patient care. Teaching of this body of knowledge at various pre- and postdoctoral medical and scientific levels of understanding provides a unifying component to laboratory and clinic.
