37185 - Histology and Embryology 1 (AK-A)

Learning outcomes

At the end of the course, the student has the skills in the morpho-functional organization of the various cell types, of subcellular structures and extracellular components constituting the human tissues. Moreover he has the skills on their stem progenitors, on cellular proliferation and differentiation as well as on the mechanisms of histogenesis, tissue renewal and regeneration. The student knows the embryology, its regulatory mechanisms and major alterations.

Teaching methods

The course consists of 5 UC of lectures including 2 UC of Cytology held by Professor Marcella Martinelli (see the teacher's website) and 3 UC of Histology which aim to make students acquire the topics described in detail in the program.

Assessment methods

The learning assessment will include the examination of slides at light microscopy that is introductory to the oral exam. The students that have not passed are not admitted to the oral exam. The oral exam is about Cytology, Histology and Embryology in according the contents published in Histology and Embryology 1 and Histology and Embryology 2 courses. A low mark in one of the three parts precludes the whole exam. The student can choose to keep the mark of examination of slides (valid until December 2019) or to repeat it. In the opinion of the examiners, the final assessment will be the weighed average of the three results.
The online registration to the examination is mandatory.

Teaching tools

Power point presentations that will be available online as downloadable content through a reserved distribution list; username and password will be reported during the first lesson introducing the course.
