Contents
Embryogenesis, origin, phylogenesis and systematics of vertebrates. The comparative study of vertebrate features respect to 1) the body protection and support: the integumentary and the skeletal systems; 2) the metabolism processes: the digestive system and the feeding, the respiratory system, the cardiovascular system, the escretory system; 3) the integration systems: the sensorial system and the nervous system.

Educational objectives
The course is aimed to provides the anatomical, functional and molecular groundings to understand the biology and evolution of vertebrates.

The main knowledge acquired will be:
- main phases of vertebrate embryology and protected environments where they occur;
- overview of vertebrate evolutionary history, describing the main anatomical characteristics of vertebrate taxa;
- similarities and differences in the body structures of different vertebrates.

The main competence will be:
- ability to understand how the embryogenesis lays the foundations of the body structure of adult organisms;
- ability to understand the role of morphofunctional variations in evolution of the vertebrate animals;
- ability to understand the relationship between form and function and between form and evolution of vertebrates
Prerequisites
In order to be able to understand the topics of the program, students must have acquired basic knowledge of Cytology, Histology and Zoology.
Teaching methods
The course is organized in lectures on the topics listed in the program.
Learning verification modality
The exam includes an oral test consisting of an interview of about 45 minutes long aiming to ascertain student knowledge level and acquired understanding capability about the topics discussed during the course. The oral exam is also intended to test the student synthesis capability
and propriety of language.
