Autonomics of Head and Neck

Question 1

the parasympathetic preganglionic axons of the oculomotor nerve exits through the __, follow __, and synapse in __. Then postganglionic axons course with __ and innervate __.

Answer 1

superior orbital fissure
inferior divison of oculomotor nerve
ciliary ganglion (in orbit lateral to optic nerve)

short ciliary nerve (V1)
sphincter pupillae muscle, ciliary muscle

Question 2

the parasympathetic preganglionic axons of the facial nerve exits through the __, course __, and synapse in __. Then postganglionic axons course with __ and innervate __.

Answer 2

internal auditory meatus

VII goes to chorda tympani of VII which joins lingual of V3–>submandibular ganglion (hangs off lingual nerve)–>direct ganglion branches and rejoins lingual (V3)–>submandibular gland and sublingual gland

OR greater petrosal nerve in middle cranial fossa to nerve of pterygoid canal(formed by greater petrosal nerve joining deep petrosal nerve)–>pterygopalatine ganglion (in pterygopalatine fossa)–>pterygopalatine nerves to maxillary (V2) to zygomatic to lacrimal (V1) to lacrimal gland and nasal and palatine nerves of maxillary (V2) to muscous glands of nasal cavity, palate, pharynx

Question 3

the parasympathetic preganglionic axons of the glossopharyngeal nerve exits through the __, follow __, and synapse in __. Then postganglionic axons course with __ and innervate __.

Answer 3

jugular foramen
tympanic nerve through middle ear to lesser petrosal nerve (exits through foramen ovale)

otic ganglion (lies medial to V3 below foramen ovale)
auriculotemporal (V3)
parotid gland

Question 4

the parasympathetic preganglionic axons of the vagus nerve exits through the __, follow __, and synapse in __. Then postganglionic axons course with __ and innervate __.

Answer 4

jugular foramen
all branches distal to recurrent laryngeal nerve

terminal ganglia (in wall of esophagus)
nerves not named but  lie in or near wall of structure innervated
glands and smooth muscle in esophagus

Question 5

the sympathetic preganglionic axons of the ventral root and ramus of T1 exits through the __, follow __, and synapse in __. Then postganglionic axons course with __ and innervate __.

Answer 5

intervertebral foramina
white rami to paravertebral sympathetic trunk then up to

superior cervical ganglion
periarterial plexuses on carotid branches
dilatory pupillae muscle, superior tarsal muscle, sweat glands
