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.
