Course Unit Page

Academic Year 2018/2019

Learning outcomes

At the end of formative way, the student knows submicroscopic organization, and their functional aspects, of various citotypes, which constitutes human tissues. The student knows human embryology, with regulation mechanisms.

Assessment methods

The check consists of a preliminary proof at microscopy, for the identifications of histological tissues. If this proof is not sufficient, the examination does not progress.

The oral examination focuses on cytological, histological and embryological matter, according to the program of Istology and Embryology 1 and Histology and Embryology . The insufficence also in one of the three learning is not allowed.

In caso of negative result of the oral examination, the student may keep the result of the practice or make it again. The vote is valid until the appeals of december 2018.

The final votation, by determination of the Commission, considers the results obtained.

Teaching tools

Power point presentations and microscopic figures of histological tissues. Students, by means og a reserved list, may got on line material employed during the lessons.
