Learning outcomes

The whole course is intended to provide knowledge of basic sciences, as biochemistry, cell biology and genetics and physics, preparatory for further specific courses, with particular regards to concepts subsequently useful for understanding and deepening biomedical and obstetric issues.
By the end of the course students will have acquired:
- knowledge of cell biology relative to the basic mechanisms that regulate cell activities, reproduction, interactions, through the acquisition of the fundamental concepts of functional and molecular principles of cellular processes common to all living organisms;
- basic knowledge of medical genetics in order to be able to distinguish the various types of mendelian inheritance, to understand the transmission mechanisms of human genetic diseases, to estimate the genetic recurrence risks, to understand the ethical, social and medical issues relating to prenatal genetic testing;
- basic knowledge of organic chemistry and biochemistry on the structure-function relationships of the most important biological macromolecules, the metabolic regulation at the molecular level, and the energy level changes associated to different biochemical pathways;
- basic knowledge and understanding of fundamental laws of physics, particularly of mechanics and fluidodynamics, and their application in biomedical phenomena and real situations, as well as the ability to solve simple physics problems also relative to real situations, such as joints and equilibrium of bodies.
This fundamental knowledge is a prerequisite for further specializations that will be object of the following year teachings.
More details are available on the specific forms dedicated to the individual modules that constitute the teaching.

See the forms of each single module for details.

Assessment methods and criteria

The exam consists of 4 written tests, one for each module, based on all the issues covered throughout the course. Tests can be passed separately as long as they are within the same academic year.
For each academic year, 6 periods are available to take the exams: 2 in the Winter Session at the end of the course, 2 in the Summer Session and 2 in the Autumn Session.
Students who have been admitted to the undergraduate degree with a score lower than 6 points in Biology, 3 points in Chemistry and / or 3 points in Physics and Mathematics, must have first discharged their training debts, before taking the exam.
To pass the exam, students must get a score of not less than 18/30 in each test. The final mark (/out of 30) willl derive from the weighted average over credits of each single test score. Students can retire or refuse the proposed score: in such case, any partial credit will be canceled and the students shall enroll again for the whole examination (all the 4 tests).
See the forms of each single module for more details.
