HUMAN PHYSIOLOGY
The final evaluation consists in a multiple choice exam, performed through a digital support (PC), organized in 40 questions on the entire course programs. The exams is passed if the student attains a score greater than 18/30.

GENERAL PATHOLOGY
The student must pass both a written test of 31 questions to be solved in 30 minutes. The questions will be related to the course content; and will be structured on: knowledge acquisition and understanding (45%) and application of the knowledge acquired (35%), judgment autonomy (10%), and learning ability (10%).

Assessment: 
Voto Finale

The course of Human Physiology provides the Students with all information needed to understand, from the biophysical and quantitative standpoint, the mechanisms of functioning of body organs and systems and their control performed by the central and autonomic nervous system and by the endocrine system.

The General Pathology course provides the students with the fundamentals of modern cellular and molecular pathology. The course deals with the investigation of those pathological mechanisms common to all tissue-cell pathology; Etiology, Pathogenesis, Morphologic changes, Functional derangements and clinical significance. Attention is paid to the processes of cellular adaptation, cell death, cellular accumulation, tissue repair, inflammation, immunology and immunopathology, and neoplasia. This course takes the basic science that the student has learned in previous courses to clinical concepts.

The course objectives will be achieved through frontal lessons. The attendance of the lessons is obligatory.

During classroom discussions, students are encouraged to interact with teachers with questions and curiosities. During lectures, the lecturers will also present examples and daily facts that can make sense of the application / importance of the subjects of the lessons.

Professors will be available at their offices (Via Monte Generoso 71, "Ex Colonia Agricola "), after making an appointment by e-mail.
