Where is the cerebellum?

The cerebellum and the brain stem share a close space within the lower back portion of the skull. They reside above an opening at the base of the skull –- called the foramen magnum –- through which the spinal cord passes. A Chiari malformation occurs when the cerebellum is forced downward below the foramen magnum and into the spinal canal. The cerebellum controls your muscle movements, posture, balance, speech and coordination.
