  Sectional anatomy of encephalon    Basic elements of sectional geometry ã  Although classic definition of section refers only to the intersection of a surface with a plane, for the anatomical study, the sections can be considered as geometrical objects, surfaces and lines.  Thereby, we consider that: ã The intersection of an object (three-dimensional) with a plane generates a surface (two-dimensional) - for example: parenchimatous organs, fusiform muscles; ã The intersection of a surface (two-dimensional) with a plane generates a line (one-dimensional)  –  for example: the diaphragm, serous, meninges; ã The intersection of a line (one-dimensional) with a plane generates a point (zero-dimensional)  –  for example: vessels, nerves.  ã For the orientation of sections, the main axes and orientation planes of the human body must be studied. In a three-dimensional space (as the one used in human anatomy), from a certain point, three straight axes, perpendicular to each other can be drawn, which determine two by two a plane, the third one being perpendicular to this plane. Thereby: - Median plane contains vertical and anterior-posterior axes and is perpendicular to the transverse axis - Frontal plane contains vertical and transverse axes and is perpendicular to the anterior-posterior axis -Horizontal plane contains transverse and antero-posterior axes and is perpendicular to the vertical axis ã In the study of human anatomy, the most frequent sections are the ones drawn through these planes.
