Learning objectives
At the end of the course the student should
to know the methods and morphological survey tools
learn about the morphology of the cells and tissues of the human organism;
know the main mechanisms through which is realized the maturation of germ elements, fertilization and development of the human organism;
be able to observe, describe and identify the different organelles of the eukaryotic cell, the various tissues and their localization within the bodies; know: the organization of the human body, the shape and the seat of the organs of the various systems of the body and the main structural features that are the basis of organ functions
Acquire the knowledge of the morphology, microscopic and submicroscopic structure of cells and tissues, particularly with regard to those of the human organism; to know gametogenesis.
Describe the general architecture of the human body and the structure of the organs in relation to their functional role.
Know the basic use of the optical microscope for the observation of histological samples, prepared according to conventional methods.
Observe histological preparations, in order to discuss, describe and identify the morphological features of the various tissues and organs; demonstrate that the necessary knowledge for subsequent courses was acquired.
