HISTOLOGY AND EMBRYOLOGY GENERAL VETERINARY
Learning outcomes of the course unit
The module “Histology and General Veterinary Embryology “makes part of the course “Histology, Embryology and Zoology”. The module has the aim to teach the student to know and understand the notions of cytology, embryology and histology, with the purpose to gain solid basic knowledge necessary for the continuation of the educational process towards the profession of veterinary medicine.
Precisely the students need to be able to:
1. Know and understand the principles of cytology, embryology, and general histology. Be able to understand and use the appropriate scientific vocabulary. Be able to critically elaborate the acquired knowledge. (knowledge and understanding)
2. Be able to use the acquired knowledge to recognize with the optical microscope different tissues and understand the different levels of structural organization (subcellular / cellular/ tissutal); to understand the dynamics of development, starting from the gametogenesis to the formation of the three germ layers; to analyze different factors that influence the variation of the fetal circulation at birth; to understand the dynamics of the formation of the fetal membranes and placenta of veterinary species (applying knowledge and understanding)
3. The students at the end of the lessons need to demonstrate the comprehension of the different topics introduced during the lectures and plenaries, and the ability to correlate the different structural levels. In particular, they need to be able to integrate and handle the acquired knowledge in multidisciplinary areas (making judgments)
4. The students need to demonstrate the ability to communicate clearly the knowledge acquired using adequate language (communication skills)
5. The student needs to demonstrate the ability to correlate, integrate and handle the gained knowledge in multidisciplinary areas. Additionally, they need to demonstrate to have developed abilities that make them autonomous in the handling of their knowledge (learning skills)
Specific knowledge required by the admission test and when necessary, recovery of the educational debt in Biology. (O.F.A.)
Course contents summary
The course includes theoretical lessons that take place in the classroom and theoretical-practical lessons that take place both in the histology and in the microscopy labs. The course is divided into three parts. The first part of the course dedicated to the cytology treated of the structure of eukaryotic cell. The second part give notions of general embryology from gametogenesis to germ layers formation and regarding the species of veterinary interest, covers fetal membranes, placentation, fetal circulation and changes at birth will be treated.
In the third part, that is devoted to histology, the teacher provides knowledge on structural and functional characteristics of the various tissues and on the techniques and equipment necessary for the preparation of histological slides and their analysis. In the practical lessons the student is exercised in recognition of tissues by light microscopy. For the practical activity is required the distribution of students in different groups, the number of groups is related both with the total number of students and with the labs and room capacity.
The students, in addition to the reference texts listed below, by signing in the course website, using ID and password, are going to have:
• The course contents detailed,
• Outlines to take on the theoretical and theoretical-practical activities,
• Histological microphotographs obtained from slides utilized during the practical activity,
• Histological slides of the laboratory activity are digitized and available by computer at the Veterinary Anatomical Museum,
• Link to open web sources.

The course includes theoretical lessons that take place in the classroom and theoretical-practical lessons that take place both in the histology and microscopy labs, where the students exercise to the tissues identification by light microscopy. The practical activity is organized supplying in advance to each student, through web page accessible through user and password, the work plan of the practical activity, to allow students the preparatory study. For the practical activity is required the distribution of students in different groups, the number of groups is related to the total number of students, on the lab and room capacity and allowing each student to work independently.
Assessment methods and criteria
The final exam, structured to evaluate the achievement of the objectives of the course, include a practical and an oral tests. The practical test consist on the recognition of tissues within an histological slide by the optical microscope and produce a short written with a scheme representing the observed tissue The oral examination is based on the discussion of the written scheme from the practical test and on the answers to 3 questions, one for each part of the course, randomly identified by the computer.
The exam aims to evaluate whether the student has achieved the goal of knowledge and understanding of the content and the ability to apply the knowledge gained.
The exam grade is associated with the overall assessment of the responses given by the student, weighted according to the load time of each part of the course; however, having regard to the mode of selection of questions, nowhere are permitted answers seriously insufficient (less than 4 of 10).
The examination will be completed with the second part, in the exams scheduled, with the definition of the final evaluation. Students diagnosed with learning disabilities according the law n° 170/2010, benefit the support provided to them by law.
