Flashcards in Parasympathetic Visceral Efferent Pathway Deck (6)
Which VE pathway is conveyed in C.N. III?
a parasympathetic motor pathway
VE fibers conveyed in C.N. III orginate from which nucleus?
accessory oculomotor nucleus of Edinger/Westphal
Identify the components of the parasympathetic efferent pathway of C.N. III beginning with the nucleus of origin and continuing to the target organs.
- accessory nucleus of Edinger/Westphal
- preganglionic parasympathetic efferent fibers
- oculomotor nerve
- ciliary ganglion synapse
- postganglionic parasympathetic efferent fibers
- short ciliary nerves
- sphincter pupillae and ciliaris muscles
What is the location of synapse for preganglionic parasympathetic efferent fibers of C.N. III?
Postganglionic parasympathetic efferent fibers of C.N. III are carried in which nerve?
short ciliary nerve
