English: Anatomical planes through a rotating model of a human brain with eyes but excluding optic nerves.

  The figure shows three axes annotated as follows: 
       d: Dorsoventral or Axial axis (yellow)
       l: Left-right, or lateral axis (cyan, blue-green)
       m: Medial  or anterior-posterior axis (magenta)

  The figure shows three major planes annotated as follows:
       a: Axial or horizontal plane (blue), that contains the lateral axis 
          and also the medial axis 
       c: Coronal plane (green), containing the axial axis and the lateral axis
       s: Sagittal plane (red), containing  the axial axis and the medial axis

  There also is:
       e: The eye position showing the anterior end of the brain
       p: an example of a parasagittal plane (yellow); 
          parasagittal planes comprise the class of planes 
          parallel to (and therefore lateral to) 

the sagittal plane.
