| Nucleus ambiguus | Innervates the vagus (CN X) and glossopharyngeal (CN IX) nerves, controlling pharyngeal and laryngeal muscles |
| Hypoglossal nucleus | Innervates the tongue muscles via the hypoglossal nerve (CN XII) |
| Solitary nucleus | Receives sensory input from the vagus and glossopharyngeal nerves |
| Dorsal motor nucleus of the vagus | Provides parasympathetic innervation to visceral organs |
| Pharyngeal branch | Impairs swallow initiation and pharyngeal contraction |
| Superior laryngeal nerve | Disrupts vocal cord tension and protection |
| Recurrent laryngeal nerve | Causes vocal cord paralysis and aspiration risk |
| Sensory function | Taste sensation (posterior third of tongue) |
| Motor function | Stylopharyngeus muscle (pharyngeal elevation) |
| Reflex control | Swallow and gag reflexes |
| Motor deficits | Tongue weakness, atrophy, fasciculations |
| Functional impairment | Difficulty with chewing, swallow manipulation, and articulation |
