How many sympathetic ganglia are in the head?
zero - sympathetic neurons are located in the superior cervical ganglia of the neck
What ganglion carries parasympathetic fibers associated with CN III?
ciliary ganglion
What are the smooth muscle targets of the postganglionic fibers of the ciliary ganglion?
ciliary muscle (lens) constrictor pupillae muscle (iris)
What ganglia carry parasympathetic fibers associated with CN VII?
pterygopalatine ganglion
submandibular ganglion
What ganglion carries parasympathetic fibers associated with CN IX?
otic ganglion
What nerve contains preganglionic parasympathetic fibers between the nervus intermedius and the pterygopalatine ganglion?
greater petrosal nerve
Where are postganglionic fibers from the pterygopalatine ganglion going?
lacrimal gland
mucosa of the nasal cavity
minor salivary glands of the roof of the mouth
What nerve carries preganglionic fibers between the nervus intermedius and the submandibular ganglion?
chorda tympani
Where are postganglionic fibers from the submandibular ganglion going?
submandibular gland

Where are postganglionic fibers from the otic ganglion going?
parotid gland
What nerve do the postganglionic fibers from the otic ganglion to the parotid gland hitchhike with?
auriculotemporal nerve
What nerve do the postganglionic fibers from the pterygopalatine ganglion to the lacrimal gland hitchhike with?
