(both peripheral sensory and peripheral autonomic ganglia)

Ciliary
autonomic preganglionic neurons in the Edinger-Westphal nucleus synapse on postganglionic neurons via CN 3 in the ciliary ganglion which innervate constrictor muscles of the iris and the ciliary muscle
Trigeminal (Gasserian or semilunar)
sensory ganglion to the spinal nucleus, main sensory nucleus, and mesencephalic nucleus of CN 5 from face, muscle receptors and meninges; contains pseudounipolar ganglion cells similar to those found in the dorsal root ganglia
Pterygopalatine
autonomic ganglia of CN 7 that innervate lacrimal glands and glands of nasal mucosal from the superior salivatory nucleus
Submandibular
autonomic ganglia of CN 7 that innervate salivary glands from the superior salivatory nucleus
Otic
autonomic ganglia of CN 9 that innervate parotid gland from the inferior salivatory nucleus
Geniculate
sensory ganglia of CN 7 that innervates the anterior two thirds of the tongue and palate (via chorda tympani) as well as the skin of the external ear from the solitary nucleus and the spinal nucleus of CN 5

NOTE: nerves in the chorda tympani may carry several taste sensations thus the exact signal is a compilation of ion gating and second messengers that transmit a different signal for each taste

Vestibular
sensory ganglia of CN 8 from the vestibular nuclei going to the hair cells of the vestibular labyrinth
Spiral
sensory ganglia of CN 8 from the cochlear nuclei going to the hair cells in the organ of Corti
Superior (jugular) ganglia of glossopharyngeal
sensory ganglia of CN 9 from the spinal nucleus of CN 5 to the skin of the external ear
middle ear is innervated by Jacobsen’s nerve which is a branch off of CN 9
Inferior (petrosal) ganglia of glossopharyngeal
sensory ganglia of CN 9 going from solitary nucleus to the mucous membranes of pharynx, middle ear, carotid body and sinus
sensory ganglia of CN 9 going from solitary nucleus to taste sensor on the posterior third of the tongue
Superior (rostral) ganglion of vagus nerve
sensory ganglia of CN 10 going from spinal nucleus of CN 5 to skin of external ear and meninges
Inferior (nodose) ganglion of vagus nerve
sensory ganglia of CN 10 going from solitary nucleus (caudal) to larynx, trachea, gut, and aortic arch receptors
sensory ganglia of CN 10 going from solitary nucleus (rostral) to taste receptors of the posterior oral cavity
Peripheral autonomic ganglia
autonomic ganglia of CN 10 going from dorsal motor nucleus of CN 10 to gut, respiratory structures and heart

NOTE: ala cinerea lies directly posterior to the dorsal motor nucleus
