Human Physiology and Basic Anatomy
A.Y. 2024/2025
Learning objectives
The general objective of this course is to provide the basic principles of tissue and system organization and to describe the molecular and cellular processes governing organ and system functioning, with emphasis to the human being. In particular, the course will analyze the main molecular mechanisms of cell physiology, the salient features of organ and system functioning, the main control systems and their reciprocal interaction. The acquired information will establish the basis for understanding the physiological adaptation process taking place due to a continuously changing environment.
This knowledge is essential for understanding the subsequent courses in biological and medical area and its application is the basis of pharmaceutical biotechnology.

Assessment methods and Criteria
The exam is an oral interview, and it is divided into two parts.
The first one focuses on cellular physiology and histology and consists of two questions: the first is related to the cell functioning and the other is inherent to tissue organization. The interview is passed if the candidate demonstrates that he/she has acquired and understood the principles of cell functioning and cell organization in tissues (not the simple "learning by heart"). For student attending the courses, an on-going evaluation is planned in written form (with open and multiple-choice questions) during the teaching-break (generally end of April). The exam is deemed to be passed only if the student has acquired a minimum score of 18/30.
The second part focuses on the different physiological systems. In general, the oral exam consists of three questions: the first concerning a topic that can be chosen by the student himself, the subsequent ones concerning two different apparatuses. The presentation and organization of the first topic will allow to verify the general comprehension of the subject, as well as the communication skills. The other questions will serve to verify the degree of in-depth study, and the appropriateness of the terminology.
The final mark is the weighted average (4 credits for Cellular Physiology and Histology and 6 credits for General Physiology and Anatomy) of the two marks. The evaluation is released at the end of the test and submitted to the candidate for acceptance. The assessment includes a range of: minimum marks (18-23/30) if sufficient preparation is demonstrated; intermediate marks (24-27/30) if the student shows a good knowledge of all the topics covered in the exam; high marks (28-30/30) if the student shows an excellent knowledge of all the topics covered in the exam and excellent communication skills. The student is awarded with the highest mark (30 lode) if he will demonstrate ability to deepen the topics.
