The student must be able to perform appropriate clinical-pathological correlations.
Course syllabus and organization

Single session

The lessons will be held on the Microsoft Teams platform and can be followed both synchronously on the basis of the first semester timetable and asynchronously because they will be recorded and left available to students on the same platform
Prerequisites for admission
Notions of Human Anatomy, Physics, Chemistry and Biochemistry
Assessment methods and Criteria
The exam will be exclusively written, and will consist of 30 multiple choice questions. The questions will focus on all the topics covered in class and are intended to determine the student's understanding of the given topic. To pass the exam it will be necessary to answer exactly at least 16 questions; the final grade will therefore be calculated by adding 2 to the number of correct answers.
