Physiology
Module Electromyography

Academic Year 2022/2023 - Teacher: Rosario GIUFFRIDA

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