Although not mandatory, solid foundations of Human Anatomy and Biochemistry are advisable in order to approach the study of the topics of the course of Physiology 1.

Final Examination: 

The final exam will consist of a written test that will be made at the end of the course and will include all arguments of both courses.

Voto Finale

At the end of the course the student will be in possession of the knowledge needed to understand the workings of nerve cells, of nerve circuits to which they belong, of their interaction and the various areas or districts that they form. Through such knowledge, the student will be able to develop a critical reasoning on the functioning of individual systems and on how the various parts of the nervous system interact with each other to ensure the correct control of the functional cardiovascular,respiratory and homeostatic parameters, as well as the sensory afferent information are interpreted and processed to obtain motor efferent responses consistent with the stimuli to which the organism is exposed.

The course will deal with the concepts related to the functioning of nerve cells, and subsequently the functioning of sensory systems, afferent pathways, efferent motor pathways, movement control centers and specific functions of the various brain areas
