Q

Portions of the tongue via which nerves and which ganglia?

Which nucleus does it go to?

A

Anterior 2/3 via facial (CN7) via geniculate ganglia.

Posterior 1/3 via glossopharyngeal (CN9) via inferior ganglia.

Pharynx via 10/CN11 via inferior ganglia.

Goes to nucleus of tractus solitarius.

Q

What does dorsal motor nucleus control? Which cranial nerve does it travel via?

A

Dorsal motor nucleus runs via 10/Cr11. Goes to lots of postganglionic ganglia which control secretion (pancreas, gastric glands, lungs) and cause bronchoconstriction. Not involved in heart ganglion as this comes from nucleus ambiguous.
