12

P-sym Edinger-Westphal Nucleus

Travels out on CNIII to synapse in ciliary ganglion and then continues on Va
Targets: Ciliary muscle
Iris muscle

13

P-sym Superior Salivatory Nucleus

Travels out on CNVII to synapse in pterygopalatine ganglion then continues on Vb-Va to lacrimal glands

14

P-sym Superior Salivatory Nucleus

Travels out on CNVII to synapse in pterygopalatine ganglion then continues on Vb to nasal/palatine glands

15

P-sym Superior Salivatory Nucleus

Travels out on CNVII to synapse in submandibular ganglion then continues on Vc to submandibular/sublingual glands

16

P-sym Inferior Salivatory Nucleus

Travels out on CN IX to synapse in otic ganglion and then continues on Vc to parotid gland (secretory motor)

17

P-sym Dorsal motor of vagus

Travels out on CN X to cardiac/myenteric ganglion and continues on Vagus Nerve to heart, foregut and midgut
