Answer 2

Ciliary Ganglion

Question 3

What is the target/action of the parasympathetic postganglionics from the Edinger-Westphal nucleus (originally)?

Answer 3

Eye (sphincter pupillae and ciliaris muscle) for pupillary contraction

Question 4

Preganglionic parasympathetic fibers from the superior salivatory nucleus travel with what cranial nerve?

Answer 4

CN VII (facial)

Question 5

Preganglionic parasympathetic fibers from the superior salivatory nucleus synapse in what peripheral ganglia?

Answer 5

Pterygopalatine and submandibular ganglia

Question 6

What is the target/action of the parasympathetic postganglionics from the superior salivatory nucleus (originally)?

Answer 6

Lacrimal glands and salivary glands (increased tears and salivation)

Question 7

Preganglionic parasympathetic fibers from the inferior salivatory nucleus travel with what cranial nerve?

Answer 7

CN IX (glossopharyngeal)

Question 8

Preganglionic parasympathetic fibers from the inferior salivatory nucleus synapse in what peripheral ganglion?

Answer 8

Otic Ganglion

Question 9

What is the target/action of the parasympathetic postganglionics from the inferior salivatory nucleus (originally)?

Answer 9

Parotid gland (increase salivation)

Question 10

Preganglionic parasympathetic fibers from the Dorsal motor nucleus travel with what cranial nerve?

Answer 10

CN X (vagus)

Question 11

Preganglionic parasympathetic fibers from the dorsal motor nucleus synapse in what peripheral ganglia?

Answer 11

Thoracic visceral plexus or paravertebral plexus

Question 12

What is the target/action of the parasympathetic postganglionics from the dorsal motor nucleus (originally)?

Answer 12

Thoracic and abdominal viscera to the level of the colic flexure (constrict airway and increase gut motility)

Question 13

Preganglionic parasympathetic fibers from the nucleus ambigus travel with what cranial nerve?

Answer 13

CN X (vagus)

Question 14

Preganglionic parasympathetic fibers from the nucleus ambigus synapse in what peripheral ganglion?

Answer 14

Thoracic visceral plexus

Question 15

What is the target/action of the parasympathetic postganglionics from the nucleus ambigus (originally)?

Answer 15

Cardiac muscle (decrease CO and BP)

Question 16

Preganglionic parasympathetic fibers from the lateral horn of S2-S4 travel with what nerves?

Answer 16

Pelvic Splanchnic Nerves

Question 17

Preganglionic parasympathetic fibers from the lateral horn of S2-S4 synapse in what peripheral ganglion?

Answer 17

paravertebral plexus

Question 18

What is the target/action of the parasympathetic postganglionics from the lateral horn of S2-S4 (originally)?

Answer 18

Descending colon and pelvic viscera (stimulates digestion, stimulates peristalsis, relax sphincters, increase secretions, stimulate bladder/relax sphincter, stimulates erection)
