Flashcards in Anatomy and Physiology XXII Deck (25)
1

What is controlled by the nucleus ambigiuus?

Motor innervation of the pharynx, larynx, and upper esophagus (e.g. swallowing, palate elevation) (p.435)

2

What cranial nerves receive innervation from the nucleus ambiguus of the vagal nuclei?

CN IX, X (p.435)

3

What cranial nerve receives innervation from the dorsal motor nucleus of the vagal nuclei?

CN X (p.435)

4

What is the function of the dorsal motor nucleus?

To send sutonomic (parasympathetic) fibers to the heart, lungs, and upper GI (p.435)

5

What is the principle difference in functions controlled by the nucleus solitarius vs nucleus ambiguus?

Nucleus solitarius- visceral sensory information; nucleus ambiguus- motor innervation (p.435)
