Solution

failed
failed

The answer is (B) False.

Explanation for each cranial nerve and its function:

  1. I (Olfactory Nerve): Correctly matched to smell identification.
  2. II (Optic Nerve): Correctly matched to visual acuity, visual fields, and fundi.
  3. III (Oculomotor Nerve), IV (Trochlear Nerve), VI (Abducens Nerve): Correctly matched to eye movements.
  4. V (Trigeminal Nerve): Correctly matched to jaw muscle palpation and facial sensation.
  5. VII (Facial Nerve): Correctly matched to facial movements.
  6. VIII (Vestibulocochlear Nerve): Incorrectly matched. The whispered voice test is a hearing test, which is part of the function of the vestibulocochlear nerve, but it also includes balance, which is not mentioned.
  7. IX (Glossopharyngeal Nerve), X (Vagus Nerve): Correctly matched to the gag reflex.
  8. XI (Accessory Nerve): Correctly matched to the strength and symmetry of the upper trapezius shrug.
  9. XII (Hypoglossal Nerve): Incorrectly matched. The hypoglossal nerve is responsible for tongue movements, not word articulation. Word articulation involves multiple cranial nerves, including the hypoglossal nerve, but also the facial nerve (VII) and the vagus nerve (X).

Therefore, the table contains inaccuracies, making the statement false.
