Correlates to the TEA
What is the petrous ridge/petrous apex?
The six (6) fontanels that occur in the infant skull
What are the anterior, posterior, right sphenoid, left sphenoid, right mastoid, and left mastoid?
Measurements for skull width are taken between the ______________________. Measurements for skull length are taken between the ____________________ and the ______________________.

Superior rim of the bony orbit of the eye
What is the supraorbital margin (SOM)?
Junctions of the upper and lower eyelids
What are canthi?

In adults, the anterior end of the sagittal suture is the __________ and the posterior end is the __________. The right and left ________________ are at the posterior end of the sphenoparietal articulation. The right and left ________________ are points posterior to the ear where the squamosal and lambdoidal sutures meet.
