Nerve that passes through the internal acoustic meatus?
The facial nerve (cranial nerve VII) passes through the internal acoustic meatus. It carries motor fibers to the muscles of facial expression and also carries taste sensations from the anterior two-thirds of the tongue.
Which taste sensations could be lost after damage to the facial nerve?
Loss of taste sensations that could result from damage to the facial nerve include the inability to taste sweetness on the anterior two-thirds of the tongue due to dysfunction of the chorda tympani branch of the facial nerve, which carries taste information.
