Which cranial nerves are in which LOBE of the brain?
The cranial nerves (with the exception of I and II) originate in the brainstem, which includes the midbrain, the pons, and the medulla. CNI receptors of cranial nerve I and electrical activity is transduced into the olfactory bulb. Olfactory bulb cells then transmit electrical activity to other parts of the central nervous system via the olfactory tract. CNII The optic nerve exits the back of the eye in the orbit and enters the optic canal and exits into the cranium. It enters the central nervous system at the optic chiasm (crossing) where the nerve fibers become the optic tract just prior to entering the brain. The link below has a chart of what CN goes to what part of the stem. Hope that helps.
