Chapter 7 - Lower cranial nerve function. The lower cranial nerves are involved in pharyngeal and laryngeal function as well as in movements of the neck and tongue. Damage usually manifests as problems with speech and swallowing. These nerves arise from the medulla and, in the case of the accessory nerve (CN XI), the spinal cord. These nerves are commonly affected by conditions damaging the medulla, but bilateral damage to corticobulbar connections can create motor problems that affect tongue and pharynx movement and speech.
Best Answer: There are three cranial nerve involved in taste... The Facial Nerve carries information from the front 2/3 of the tongue. (Cranial Nerve VII) The Glossopharyngeal Nerve carries information from the back 1/3 of the tongure (Cranial Nerve IX) The Vagus Nerve also carries some taste information, but it's a minor component (Cranial Nerve X).
