In fish, the hypoxic signal is carried up to the brain for processing by the branchial arch is innervated by the glossopharyngeal nerve ( cranial nerve IX ); however all four arches are innervated by the vagus nerve ( cranial nerve X ).

The internal carotid plexus communicates with the trigeminal ganglion, the abducent nerve, and the pterygopalatine ganglion ( also named sphenopalatine ); it distributes filaments to the wall of the internal carotid artery, and also communicates with the tympanic branch of the glossopharyngeal nerve.
43.
Posterior to it, near its origin, is the superior laryngeal nerve; and higher up, it is separated from the internal carotid by the Styloglossus and Stylopharyngeus, the glossopharyngeal nerve, the pharyngeal branch of the vagus, and part of the parotid gland.
44.
Cranial nerves that control the muscles relevant to dysarthria include the trigeminal nerve's motor branch ( V ), the facial nerve ( VII ), the glossopharyngeal nerve ( IX ), the vagus nerve ( X ), and the hypoglossal nerve ( XII ).
45.
The mucous membrane of the middle ear is supplied by a bunch of nerves called the tympanic plexus, which mainly originates from the tympanic branch of the glossopharyngeal nerve, and, you guessed it, the glossopharyngeal nerve also carries sensory information from the pharynx and the posterior S ! of the tongue.

The mucous membrane of the middle ear is supplied by a bunch of nerves called the tympanic plexus, which mainly originates from the tympanic branch of the glossopharyngeal nerve, and, you guessed it, the glossopharyngeal nerve also carries sensory information from the pharynx and the posterior S ! of the tongue.
47.
The "'lesser petrosal nerve "'( also known as the "'small superficial petrosal nerve "') is the General visceral efferent ( GVE ) component of the glossopharyngeal nerve ( CN IX ), carrying parasympathetic pre-ganglionic fibers from the tympanic plexus to the parotid gland.
48.
Taste cells synapse with primary sensory axons that run in the chorda tympani and greater superficial petrosal branches of the facial nerve ( cranial nerve VII ), the lingual branch of the glossopharyngeal nerve ( cranial nerve IX ), and the superior laryngeal branch of the vagus nerve ( Cranial nerve X ) to innervate the taste buds in the tongue, palate, epiglottis, and esophagus respectively.
49.
From the plexus, branches are distributed to the muscles and mucous membrane of the pharynx ( except the stylopharyngeus, which is innervated by the glossopharyngeal nerve ( CN IX ) ) and the muscles of the soft palate, except the Tensor veli palatini, which is supplied by the nerve to tensor veli palatini, a branch of the nerve to medial pterygoid ( which itself is a branch of the mandibular nerve-CNV / 3 ).
50.
Any substance that can diffuse through the eardrum, ( and it really only has to get to the inner surface of the eardrum, which is covered by the mucous membrane of the middle ear, and therefore innervated by the glossopharyngeal nerve ) might cause a degree of chemical irritation to the mucous membrane, which would generate a sensory impulse the brain could well interpret as a taste-the brain's differentiation of smell, taste and oropharyngeal stimuli being a bit fuzzy .-- Mattopaedia 13 : 30, 20 September 2006 ( UTC)
