The course aims at providing useful stimuli student learning the anatomy and physiology basis of the eukaryotic cell. We want offer the opportunity to learn and use proper and rigorous scientific language and a method of study that tends to favor the understanding of the relationship structure / function exists for each component or cellular compartment. Another aim of the course is to offer students of scientific criticism instruments to be able to read independently and critically a scientific work.

D1- KNOWLEDGE AND UNDERSTANDING When the course is over, to pass the exam, students must demonstrate that they have acquired the knowledge about the general concepts of living matter: the cellular modifications due to a stimulus, the intra- and extra-cellular communication pathways, the application of cellular communication "in vitro" and "in vivo", the Mendelian’s genetics foundations.

D2- CAPACITY 'TO APPLY KNOWLEDGE AND UNDERSTANDING The student will demonstrate the ability to identify the most common mechanisms of cellular communication.

D3- JUDGEMENT The student will have acquired knowledge to favor the understanding of the structure / function relationship exists for each component or cellular compartment and their application in various biological systems.

D4- communicative skills The student will have the ability to relate in a professional and competent manner with public and private entities. The student will have the ability to transmit the knowledge acquired in a clear and understandable and accessible to unqualified persons.

D5- LEARNING ABILITY The student will be able to examine and understand scientific texts, will also have to demonstrate that they have learned a fair and rigorous scientific language and a method of study that employ them in everyday contexts for the profession and for research.

Other recommended textbooks will be provided at the beginning of the course.

Assessment

Oral examination.The abilities of the student will be evaluated according to Dublin Descriptors.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
