Learning outcomes
After attending this course and passing the final exam, the student knows cytology, histology, anatomy and physiology of the skin and skin annexes, and the morphological and functional changes associated with the aging processes.

Teaching methods
Lectures supported by powerpoint presentations of each topic of the course will be shown.
Assessment methods
Student learning in the Integrated Course “Skin and skin annexes Anatomy and Physiology” will be assessed in two oral tests, both of them evaluated in thirtieths; students must have passed the first test to take the second one. 1) The first test concerns the teaching module "Skin and skin annexes Anatomy"; 2) the second test (which can be taken on the same day or later, within twelve months) concerns the teaching module "Skin and skin annexes Physiology". Each test is passed if the mark is equal to or higher than 18/30; the final mark is the arithmetic average of the marks reported in the two tests.
Teaching tools
video, computer, power point presentations.
