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.
