Structures found at the base of the skull are for example. We ll go over how these nerves are. The sphenoid bone is a butterfly shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones. We ll look at three openings that pass forwards two openings that pass downwards and one that in spite of appearances passes obliquely backwards.

Or temporal squama pars squamosa. Now we ll move on to take a look at the openings in the floor of the anterior and middle cranial fossa that we saw earlier.
