A

a parasympathetic motor pathway

2
Q

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

A

accessory oculomotor nucleus of Edinger/Westphal

3
Q

Identify the components of the parasympathetic efferent pathway of C.N. III beginning with the nucleus of origin and continuing to the target organs.

A
  • 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
  • synapse
4

A

short ciliary nerve

6
Q
