Except that didn't make sense because all the "holes" there have nerves and vessels coming through them, not muscles, but the book said the temporal fenestra is the portal for the cheek muscles. I was determined to figure out where ours is.
So, being the smart cookie that I am, I figured out that it had to be the zygomatic arch. (The "hole" made between the zygomatic arch and the rest of the skull). And I didn't even look it up online. :)
The masseter muscle and temporalis muscle go behind the zygomatic arch down to the mandible and do their thing for mastication (that's chewing for you non-science types).

The masseter muscle actually originates on the medial side of the zygomatic arch itself and inserts roughly the same place as the temporalis muscle.
So there ya go...mastication muscles go behind the zygomatic arch - our temporal fenestra. :D
