MBB: Practice Practical Exam (HeadandNeckAnatomy)

MBB: Practice Practical Exam (Head and Neck Anatomy) • Important Notes:

• This exam was created for SMD 23 when we didn’t meet in the lab during the COVID closure. Most of the questions on this exam are duplicates of the questions on thepractice practical exam that is setup in the lab. In addition, this practice exam ONLY contains questions regarding head and neck anatomy (no neuroanatomy).

• If you are asked about an innervation in a question, the question will clearly state whether you should name a CRANIAL NERVE or a NERVE. A “NERVE” is a named branch of a cranial nerve. For our exam purposes, “CRANIAL NERVES” will include V1, V2, and V3. An answer for a “cranial nerve” innervation question will never be trigeminal (CN V).

• The answers are on the last slide (#35). For ease of reference and navigation, the numbering on the answer key correlates to the slide number on which the question is written.
