The Fundamental Sciences section refers to the preclinical specialties, the ones that, as medical students, we have the first contact with when entering medical school. These range from the specialties that present the normal, physiological state of the human body (Anatomy, Physiology, Histology) to those that offer insight into the normal mechanisms that take part in the human organism and the possible pathologies (Biochemistry, Biophysics, Immunology, Genetics), those dealing with the pathological side (Microbiology, Anatomical pathology, Physiopathology) and those presenting the wide variety of pharmacological agents involved in the treatment of each pathology (Pharmacology, Alergiology, Toxicology).
