Sensory innervation anterior to the eustachian tube opening is via the maxillary division of the trigeminal nerve (CN V2)

Nasopharynx : Sensory innervation anterior to the eustachian tube opening is via the maxillary division of the trigeminal nerve (CN V2). The glossopharyngeal nerve (CN IX) provides posterior sensory innervation. Muscles originating in the nasopharynx receive their motor supply from the vagus nerve (CN X), except for the tensor veli palatini muscle, which is supplied by the mandibular division of the trigeminal nerve (CN V3)

Hypopharynx : Motor innervations of the superior and middle constrictors are by the superior pharyngeal nerve and the pharyngeal branches of the vagus and glossopharyngeal nerves. Innervation of the inferior constrictor is from the external and recurrent branches of the vagus nerve. Sensory innervation of the pyriform sinus is from the internal branch of the superior laryngeal nerve
