Methodology: The basic material of veterinary physiology is available in the 2 volumed lecture notes written by the teachers of the department. The practical handbooks are also written by the teachers of the department. At the lectures we use transparent sheets and slides. The practical teaching activity consists of direct experiments on the living animals, observation on the living animals, experiment demonstration using semialternative methods, laboratory experiments and seminars using videorecording and computer immagination.
Assesment: Practical work is assesed throughout the course and includes two short research report presentation (one page extention, 5 minute limited presentation by students).
Exams: The final examination includes theoretical and practical materials of three semesters. The final examination consists of two parts. In the first part students take the practical exam in which are given and must solve practically problem. This exam is evaluated before the oral exam. In the course of the oral exams students are given 3 questions choisen from 175 questions, these are divided to three part. There are 30 minutes for the elaboration. Answers can be given in an optimal order. If the candidate id not able to answer the one question, we have second and third examination time.
