1

Which VE pathway is conveyed in C.N. III?

a parasympathetic motor pathway

2

VE fibers conveyed in C.N. III orginate from which nucleus?

accessory oculomotor nucleus of Edinger/Westphal

3

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

- postganglionic parasympathetic efferent fibers
- short ciliary nerves
- sphincter pupillae and ciliaris muscles
- synapse

4
