    OVERVIEW

    The course aims at providing students with the basic knowledge of the morphological and functional characteristics of human tissues with special regard to cells composing them. The course will also deal with the fundamental processes of embryonic development. Tutorials devoted to observation of histological preparations by optical microscope will deepen the aspects discussed in the lessons.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Knowledge of the main morphological and functional characteristics of human tissues with special regard to cells composing them. Knowledge of the fundamental processes of embryonic development and the major molecular mechanisms that regulate them.

    TEACHING METHODS

    The course includes classroom teaching lessons on topics of citology, histology and embryology.

    It is possible that the method of conducting the lessons will change due to emergency situations that prevent the performance of the lessons in attendance. In this case the lessons will be carried out through the Teams platform
