ANATOMIA COMPARATA ED EVOLUZIONE BIOLOGICA 3
Module ANATOMIA COMPARATA

Academic Year 2026/2027 - Teacher: VENERA FERRITO

Expected Learning Outcomes

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

 Knowledge and understanding – By the end of the course, students should demonstrate an understanding of the anatomical and morpho-functional organisation of the groups belonging to the subphylum of Vertebrates, from a comparative and evolutionary perspective. They should be familiar with the fundamental stages of embryonic development, from gametogenesis to organogenesis, in vertebrates. Identify the macroscopic and microscopic characteristics of the various organ systems. Interpret the morphological diversity of vertebrates within an appropriate phylogenetic context.

Ability to apply knowledge and understanding – By the end of the course, students should be able to use the methodological concepts of comparative analysis as a scientific tool to analyse animal anatomical structures; to correlate the concepts of descriptive anatomy and embryology in order to interpret the stages and mechanisms of vertebrate evolution; to apply knowledge of descriptive anatomy and organ function in the recognition and description of anatomical specimens and models observed during laboratory sessions. Apply models of circulation, respiration and osmoregulation to explain the adaptation of different taxa to specific environments (freshwater, marine or terrestrial environments).

Independent judgement – By the end of the course, students must demonstrate that they are able to independently assess the biological and ecological mechanisms that drive evolutionary and adaptive processes in animals; to interpret structural changes in organs as functional responses to selective pressures from the environment; and to form critical judgements on the relationships of homology and analogy between the anatomical components of different classes of vertebrates.

Communication skills – By the end of the course, students must be able to present the morpho-functional diversity of vertebrates within a phylogenetic context in a clear, rigorous and structured manner; to use the specific technical and scientific terminology of comparative anatomy and developmental biology appropriately; and to describe complex biological processes using appropriate scientific language.

Learning skills – By the end of the course, students should have developed the ability to independently consult and study advanced scientific texts on anatomy, as well as the capacity to keep their methodological knowledge up to date by integrating macroscopic anatomical knowledge with the findings of new research conducted in the fields of molecular embryology and phylogeny

Learning Assessment

Learning Assessment Procedures

The final oral examination will be preceded by a preliminary written test, comprising 10 multiple-choice questions, 2 open-ended questions and 1 diagram. Each multiple-choice answer will be worth 1 mark, whilst answers to the open-ended questions will be marked on a scale of 0 to 7 and the diagram on a scale of 0 to 6, taking into account the completeness and relevance of the answer.

Examples of frequently asked questions and / or exercises

1. Example of a multiple-choice question:

What are placodes (1 correct answer):

a) Thickening of the endoderm located in the head and neck region

b) Sensory cells associated with the sense organs

c) Vesicles associated with the sense organs

d. Thickening of the ectoderm located in the head and neck region
