Incorrect Since this bone is complex and centrally located, parts of the sphenoid are encountered in almost every significant juncture of the skull. The bone itself consists of a body and its processes along with a number of features and openings and NOT few features or openings. Both of these factors allow the sphenoid bone to be noted from various viewpoints of the skull and NOT one viewpoint. Thus it is one of the more difficult bones of the skull to describe and visualize.

9. From recent studies concerning chronic sinus infection, new concepts of its etiology and treatment have been discovered. What are these new concepts? (Select all that apply.)
ANS: A, D
Feedback
Correct Recent studies have found that the cause of chronic sinus infections lies in the nasal mucus. This suggests a beneficial effect of treatments that target primarily the underlying and presumably damage-inflicting nasal and sinus membrane inflammation.
Incorrect Recent studies have found that the cause of chronic sinus infections lies NOT in the nasal and sinus tissue targeted by standard treatment. This suggests that treatments should NOT target the secondary bacterial infection that has been the primary target of past treatments for the disease.
