COMPARATIVE ANATOMY AND BASIC EMBRIOLOGY

The teaching aims to provide an insight into the anatomical and morpho-functional organization of vertebrates through a comparative approach . Macro and microscopic characters of organs will be analyzed within an evolutionary context. The theoretical description of each apparatus will be accompanied by the analysis of anatomical models during practical laboratories. The students will then have to acquire detailed knowledges morpho-functional of vertebrates using the basic concepts of comparative surveys as scientific methodology.

Expected results - To have undergraduates know both the organization and functioning of the vertebrates body on the basis of the ontogenesis of the anatomical structures within a phylogenetic context; and to have them acquire the basic relationship between form and function. To develop autonomy of judgment on the biological mechanisms that drive evolutionary and adaptative processes in animals.- To develop communication skills using a specific technical-scientific terminology.

Lectures and laboratories

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
