- A. Supplies motor branches to the muscles of facial expression
- B. It has no sensory component
- C. The muscles of the eyelid will be spared in upper motor neuron lesions
- D. It is a nerve of 2nd arch
Explanation
The facial nerve does have a sensory component through the nervus intermedius, carrying taste and limited somatic sensation, so the statement that it has no sensory component is false. Its other listed features are correct, including sparing of the upper facial muscles in a typical unilateral upper motor neuron lesion.
