Voto Finale

The course of Human Physiology provides the Students with all information needed to understand, from the biophysical and quantitative standpoint, the mechanisms of functioning of body organs and systems and their control performed by the central and autonomic nervous system and by the endocrine system.

The General Pathology course provides the students with the fundamentals of modern cellular and molecular pathology. The course deals with the investigation of those pathological mechanisms common to all tissue-cell pathology; Etiology, Pathogenesis, Morphologic changes, Functional derangements and clinical significance. Attention is paid to the processes of cellular adaptation, cell death, cellular accumulation, tissue repair, inflammation, immunology and immunopathology, and neoplasia. This course takes the basic science that the student has learned in previous courses to clinical concepts.
