Answer to Barbie and Ken
Correct answer is D. Ken is described as not having a sense of smell due to his surgery to remove a meningioma. Hence, to correctly answer this question, students must focus on areas of the skull that are covered by meninges. This fact eliminates the possibility of answering C as correct, the nasal cavity is not lined with meninges. The epithelium of the nasal cavity is considered nasal epithelium. Of the remaining possible answers, answer D indicates the crista terminalis which is associated with the cribriform plate of the ethmoid bone. The olfactory bulbs sit here and they likely were damaged during removal of the meningioma.
