The tutorial examines the anatomy of the spinal cord and brain, their membranes and the anatomy of the pathways. A description is given of the derivatives of each cerebral bladder according to a certain scheme: the structure of the ventral surface, dorsal surface and cross sections of this part of the brain at different levels. When describing the anatomy of the pathways, attention is drawn to the location of the neurons involved in the pathway and the levels of intersection of the pathway. Knowledge of these facts is of great importance for the correct topical diagnosis in clinical practice. The presentation of the material is made using annotated diagrams and drawings with brief textual explanations.
