- a Down posterior through superior saggital sinus of the falx cerebri. then through the transverse sinus of the tentorium cerebelli. then to the internal jugular vein.
- b 1. Cochlear (for hearing) in the spiral part of the middle ear goes to the spiral ganglion (cell bodies)
2. Vestibular (balance) in the vestibular appartus goes to the vestibular ganglion (cell bodies)
Axons from both of these converge to leave middle ear to the brain.

Down- Inferior oblique and superior rectus
- d 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.
