Flashcards in Parasympathetic Nervous System Deck (18):
1

Preganglionic parasympathetic fibers from the Edinger-Westphal nucleus travel with what cranial nerve?

CN III (occulomotor)

2

Preganglionic parasympathetic fibers from the Edinger-Westphal nucleus synapse in what peripheral ganglion?

Ciliary Ganglion

3

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

Eye (sphincter pupillae and ciliaris muscle) for pupillary contraction

4

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

CN VII (facial)

5

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

Pterygopalatine and submandibular ganglia

6

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

Lacrimal glands and salivary glands (increased tears and salivation)

7

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

CN IX (glossopharyngeal)

8

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

Otic Ganglion

9

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

Parotid gland (increase salivation)

10

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

CN X (vagus)

11

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

Thoracic visceral plexus or paravertebral plexus

12

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

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

13

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

CN X (vagus)

14

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

Thoracic visceral plexus

15

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

Cardiac muscle (decrease CO and BP)

16

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

Pelvic Splanchnic Nerves

17

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

paravertebral plexus

18

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

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