- Explain the function of the pterygopalatine ganglion.
- Explain the peripheral pathway of the CNVII- oculomotor nerve.
- What is the difference between the optic nerve and the optic track? How does crossing work in the nerves of the optic nerve.
- a Extorsion: Inferior oblique and rectus
Intorsion: Superior oblique and rectus
- b Optic Nerve: eye to chiasm
Optic Tract: chiasm to brain
Nasal portion nerves cross in chiasm while the lateral portions do not. Thus left field processed by right side of the brain and vice-versa.

Opthalmic- sensation to forehead and cornea
Maxillary- sensation to maxillary and upper teeth
Mandibular- sensation to madible and works chewing muscles
