Learning outcomes of the course unit
The General Physiology course is predominantly centred on cellular physiology since it is at the level of the individual cell that, albeit with different methods, the life processes in their most general meaning are found.
The main objective of the course is to provide basic knowledge on the functions of eukaryotic cells, in their differentiated and specialized phenotypes, and on the molecular mechanisms that enable life processes to take place at cellular level.
A second objective is to provide the bases for understanding some aspects of the integration processes that, in multicellular organisms, allow the different types of cells, the constituent elements of tissues and organs, to carry out specific functions in a coordinated way.

The course is carried out through classroom lectures. At the end of each section of the course, students are given self-assessment tests.
The final assessment consists of a written test and subsequent oral discussion of the paper.
