HUMAN PHYSIOLOGY –
The final evaluation consists in a multiple choice exam, performed through a digital support (PC), organized in 40 questions on the entire course programs. The exams is passed if the student attains a score greater than 18/30.
MEDICAL GENETICS
The final evaluation consists of an oral examination
The final grade will be the average of the two single examinations
The Course is organized in a section of Human Physiology and in one of Human Genetics.
The aim of the course of Human Physiology is to provide the students with all necessary information to understand, from the quantitative and biophysical standpoint, the mechanisms of functioning of cells, tissues, and organs under normal conditions and their control by the central and autonomous nervous systems.
The objective of the Course of Medical Genetics is to provide the students with the milestones of knowledge of the genic and chromosomics mechanisms leading to the development of human pathologies

For the course, the students will have front lessons with slides. During classroom discussions, students are encouraged to interact with teachers with questions and curiosities. During lectures, the lecturers will also present examples and daily facts that can make sense of the application / importance of the subjects of the lessons.
Students are required to attend the lessons as set out in the teaching regulations of the course and sign the attendance sheet to be able to take the exam.
Professors are available for the students through appointment set through the their institutional e-mail address.
