Università Roma Tre

Knowledge and understanding: Knowledge of the principles of cell biology and tissue organization. Acquisition of conscious judgment autonomy with reference to: evaluation, interpretation and contextualization of photographs acquired with microscopic techniques. Ability to communicate effectively and with the correct terminology;
Applied skills: The basic knowledge acquired through the study of cytology will allow students to apply them to the study of tissues. In addition, students will be able to recognize and comment on a preparation or photograph acquired with a microscopic instrument. Finally, this knowledge will allow students to understand the disciplinary insights that will be carried out in the following years.
