Olfactory nerve
- nerve tract, not nerve
- primary neurons are receptor cells in epithelial of nasal cavity, axons pierce cribriform plate of ethmoid bone
- outgrowth of cerebrum
eye orbit is composed of what nerves
II, III, IV, V1, V2, VI
eye orbit is composed of what vasculature
ophthalmic a., retinal a., superior and inferior ophthalmic v.
optic nerve
- nerve tract, not nerve
- primary neurons are receptor cells in retina
- outgrowth of diencephalon
oculomotor nerve
somatomotor - superior, medial, inferior rectus mm. - inferior oblique mm. - levator palpebrae superioris m visceromotor - carries pre-ganglionic parasympathetic fibers from brain to ciliary ganglion - post-ganglion travel eyeball - constrictor pupillae m., ciliary m.
trochlear nerve
somatomotor to superior oblique m.
abducens nerve
somatomotor to lateral rectus m.
trigeminal nerve
