Questions

Please follow the format of the example, and be sure to put your questions both in the question section, and in the
answer section below with the correct answer in bold (please rewrite the whole question with the answer, not
just the number and the answer). Everyone is expected to contribute a minimum of 2 questions on the topics
Skull and Orbital Cavity. Please feel free to make as many as you want (the more you make the more questions
everyone will have!)

The answers to all questions need to be found in either the class slides or Gray’s Anatomy. These questions should
be unique, and not recycled exam questions.
