Good quiz. I have a few suggestions: maxilla should be accepted for jaw bone as well as mandible - unless you specify the lower jaw. It's not logical to demand that we reproduce a word given in the question - for example for question O, we should not have to write "nerve" as you've already given that. You have spelled "Xiphoid" incorrectly and again "Process" should not be required. For the final question, in medicine we frequently refer to the bone simply as the "Zygoma" and that ought to be accepted.
