Editing Cranial nerves (section)

====Exiting the brainstem====
With the exception of the olfactory nerve (I) and optic nerve (II), the cranial nerves emerge from the [[brainstem]]. The oculomotor nerve (III) and trochlear nerve (IV) emerge from the [[midbrain]], the trigeminal (V), abducens (VI), facial (VII) and vestibulocochlear (VIII) from the [[pons]], and the glossopharyngeal (IX), vagus (X), accessory (XI) and hypoglossal (XII) emerge from the [[Medulla oblongata|medulla]].<ref name=OBER1998>{{cite book|last2=Ober|first1=Frederic H. |last1=Martini |first2=William C.|title=Fundamentals of anatomy and physiology|year=1998|publisher=Prentice Hall International|location=London|isbn=978-0-13-010436-6|pages=474–485|edition=4th | others=coordinator, art; photographer, illustrator, Claire W.

The olfactory nerve (I) and optic nerve (II) emerge separately. The olfactory nerves emerge from the [[olfactory bulb]]s on either side of the [[crista galli]], a bony projection below the [[frontal lobe]], and the optic nerves (II) emerge from the lateral colliculus, swellings on either side of the [[temporal lobe]]s of the brain.<ref name=OBER1998 />
