Degree course: 
Corso di Long single cycle degree (6 years) in Medicine and Surgery
Academic year when starting the degree: 
Academic year in which the course will be held: 
First Semester
Standard lectures hours: 

To be admitted to the final exam of Human Physiology it is necessary to possess a positive evaluation of the exams of Human Anatomy and of Biochemistry

The final exam will be based on the syllabi of Fisiologia Umana 1 and 2. The final exam will consist of a written exam made of 40 multiple choice questions. Students that will score more than 18/30 will be subjected to an oral exam (viva). The final mark will be given on the basis of the viva alone.

Course objective and learning target
The objective of the Corse of Human Physiology is to provide to the Students 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.

Final exam
After completing the Course of Physiology 1 and Physiology 2, the student will give a multiple choice exam, performed through a digital support (PC), consisting in 40 questions on the entire Physiology 1 and Physiology 2 courses programs'. If the student attains a score greater than 18/30, the first part of the exam is passed and is follwed by an oral exam consisting of 4 open questions on the entire Physiology 1 and Physiology 2 courses programs'.
