Learning objectives
-The knowledge of the mechanisms by which the human organism obtains and maintains the homeostasis at level of cell and tissue, the mechanisms of transport and communication and the basal metabolism.
-The knowledge of the functional mechanisms of the human body organs (and in particular of the mouth), the knowledge of their dynamic integration in apparatuses and the general mechanisms of functional control.
Moreover, the student should acquire the capacity to apply the knowledge to the clinic pactice. He should acquire the capacity of deepening and updating the arguments.

Assessment methods and criteria
Oral examen
It will verified the knowledge of the General Physiology and the Physiology of organs and in particular of the mouth apparatus. It will be verified whether the student is able to establish functional relationships between the various organs, and in particular with the mouth apparatus. The knowledge of the General Physiology and Organ Physiology is the prerequisite for promotion. The vote will vary according to the knowledge of the functional relations among the organs.
