Cerebrospinal Fluid (CSF) Flow and Chiari Malformation

This is an illustration (midline view) showing the anatomical structures involved in the production and flow of cerebrospinal fluid through the ventricular system, brain and spinal cord, and finally absorption into the bloodstream. You'll also see the difference between a "normal" cerebellum and the cerebellum of an ACM patient with the cerebellar tonsils protruding through the foramen magnum.
