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
Expected learning outcomes
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.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
The assessment method includes a written test, a practical exam to recognize tissues and organs, and an oral exam; it is mandatory to pass the written test for the admission at the practical and oral exam. The written test is a multiple choice test including 40 questions in 75 minutes; each question has 5 possible answers; in the practical exam students have to observe, descibe and recognize histological samples on micrographs: one micrograph to identify tissues (histology practical) and one micrograph to identify organs (microanatomy practical); the oral exam is a discussion on the topics included in the course program. Assessment parameters: the knowledge of histology and anatomy, the ability to recognize and describe organs and tissues based on the specific microscopic characteristics, and the understanding of the organization of the human body as well as the efficacious communication of the information and with the appropriate terms will be assessed. Assessment: final mark (/30) based on the results of all tests; Communication of results: the results of the written test will be published on the Ariel website.
