The skull base is located at the base of the brain. It sits behind the eyes and above the nasal cavity—the large empty space behind the nose—and slopes down to the back of the head.

Anatomy of the skull. The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
