Which of the following is NOT typically tested as part of a cranial nerve examination?

• A. Tongue strength
• B. Olfactory function
• C. Visual acuity
• D. Spinal reflexes

Answer: (D)

Cranial nerve examination focuses on functions controlled by the nerves that originate in the brainstem and forebrain, assessing sensory and motor capabilities in the head and face. Testing tongue strength assesses the hypoglossal nerve, olfactory function checks the first cranial nerve, and visual acuity evaluates the optic nerve. Spinal reflexes, however, are mediated by spinal cord circuits and peripheral nerves, not the cranial nerves. They are part of a broader neurological exam that targets the integrity of the spinal cord and peripheral nerves, so they aren’t typically included in the cranial nerve assessment.
