Physiology
Module Physiology

Academic Year 2022/2023 - Teacher: DEBORA LO FURNO

Expected Learning Outcomes

Knowledge of the primary mechanisms by which the various organs and systems work, the manner with which they cooperate harmoniously in order to maintain the homeostasis of the internal medium.
Special knowledge relating to the stomatognathic system, from sensory and motor point of view.

Course Structure

Lectures and theoretical-practical exercises.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out on line, should the conditions require it

Required Prerequisites

Prerequisites:  Biochemistry and Anatomy exams.

Attendance of Lessons

Attendance is required.

Learning Assessment

Learning Assessment Procedures

The final test consists of an oral test that the student can take in one of the sessions on the calendar.

In itinere tests are foreseen in order to detect the effectiveness of the learning and teaching processes.
