Learning outcomes of the course unit
This course aims to give basic training for other important subjects such as, for example, physiology. The course also introduces many principles and concepts for understanding the current technologies that are useful for diagnosis and treatment.

Teaching is by means of classroom lectures, usually with the use of Power Point presentation.
Students are assessed through a written exam or oral exam, if necessary.
