Q

Cranial nerve 1 the olfactory nerve does what?

A

Carries olfactory input to the brain via the olfactory bulb and tract (after receiving the chemical stimuli from the nose). Much of this input is ultimately interpreted by the uncus of each temporal lobe.

Q

Cranial nerve 2 aka the optic nerve pair does what?

A

The optic nerve carries about a million neuron fibers back from the retina of each eye to the brain via the optic nerves, Chiasma, and tracts. The neurons near the Calcarine sulcus of each occipital lobe serve as the sight interpretation centers.
