The cranial cavity is the area inside the skull and it contains the brain
jaypee
This is a good defintion for the brain.
cranial nerves arise from the brain inside the cranial cavity.
The Thoracic cavity (above the diaphragm) & the Abdominal cavity (below).
They will open the top of the skull and take away some of the bone/skull to reveal the brain. When they are done, they will put back the bone and all is well! It is a very risky/dangerous percedure though, because you can lose your memory, bodily functions, and/or become a vegteble!

The vagus nerve (cranial nerve X) is the only cranial nerve that extends all the way down to the abdomen, providing parasympathetic innervation to organs in the chest and abdomen.
Sphenoid bone: A prominent, irregular, wedge-shaped bone at the base of the skull. The sphenoid bone has been called the "keystone" of the cranial floor since it is in contact with all of the other cranial bones.The Greek physician Galen wrote that the sphenoid bone was "like a wedge thrust between the skull and the superior maxilla."
They are all in the Abdominal Cavity.
The three dimensional space matter occupies is called it's volume.
