The Antihelix mirrors the upside-down spine and is divided into five sections: Cervical Vertebrae, Thoracic Vertebrae, Lumbar Vertebrae, and Coccyx Point. Beginning at the base is the Cervical Vertebrae which occupies ⅕ of the Antihelix. The second section is the Thoracic Vertebrae, which is above the Cervical Vertebrae and occupies ⅖ of the Antihelix. The third and last sections are the Lumbar and Sacral Vertebrae, which each occupy ⅕ of the Antihelix. The Coccyx Point is the ending point.
