OVERVIEW

The course titled "Biology II" aims to integrate the knowledge of "functional histology" and cell biology by aiming to provide students with knowledge about the organization and function of cells and human tissues with particular attention to the connection between morphology and function.

AIMS AND CONTENT

LEARNING OUTCOMES

Know structure, organization and function of different human tissues and morphological-functional characteristics of cells that compose them.

AIMS AND LEARNING OUTCOMES

In order to provide the student with a complete view of the tissue organization, basic and advanced methods for analyzing the organization of human tissues and how this organization is instrumental in ensuring full homeostatic tissue function are discussed.

The course thus aims at:

1. provide basic concepts on morphology, cellular and molecular organization of human tissues;

2. discuss in depth the cellular and molecular characteristics of the different stem cell populations in the various tissues;

3. describe the functional properties of the various tissues and cells that compose them, focusing on physiopathological aspects as well.

EXAMS

EXAM DESCRIPTION

Oral.

ASSESSMENT METHODS

The exam is oral. It is always led by the owners of the course and lasts for at least 30 minutes (typically 45 minutes). With these modes, given the long experience of examinations in the discipline, the commission is able to verify with high accuracy to achieve the educational objectives of teaching. When these are not met, the student is invited to deepen the study and to use further explanation on the part of the teacher.
