It receives upper motor neuron innervation directly via the corticobulbar tract This nucleus gives rise to the efferent motor fibers of the vagus nerve terminating in the laryngeal and pharyngeal muscles, as well as to the efferent motor fibers of the glossopharyngeal nerve (CN IX) terminating in the stylopharyngeus.
