Reference texts G.M. Pontieri - Patologia Generale vol. I, Fisiopatologia generale vol. II (Casa Editrice Piccin; V edizione)
Educational objectives The course of General Pathology includes the study of the structural changes which come about in the organism and cause diseases and the changes at molecular, cellular, tissues and organs. In particular the teaching course is aimed at the comprehension by the student:

a) the causes (etiology) exogenic, endogenic which result in structural and functional alterations in the organs;

b) the molecular and cellular mechanisms (pathogenesis) by which the etiologic agents induce the damage;

c) the processes by which the organism responds to the damage, in order to reestablish the previous integral conditions (or a new condition of equilibrium).
Prerequisites For the understanding of the course the student should have basic knowledge of cellular and molecular biology, anatomy, physiology and biochemistry
Teaching methods Lecture on subjects of the course.
Other information
Learning verification modality Oral examination: is a discussion (of 30 minutes on average), aimed at ascertaining the level of knowledge, the property of language, the understanding reached by the student and the ability to integrate and connect the content of the course followed.
