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

Practical test and oral examination

Assessment methods

The examamination includes two tests.

The first consists of a practical test where the student must describe two histological preparations by the use of optical microscope.

The second test, performing only upon the positive evaluation of the first test, consists of an oral examination that is subordinated to passing the practical test and which includes cytology questions and histology questions concerning the teaching content.
