Hi guys,

I was wondering if anyone had any tricks/tips/advice for learning where the CN exit the brain stem?

Seems to be a recurrent weak spot of mine.

Thanks in advance!

Someone made a picture form of the Rule of Four, too!

CN are named (from I to XII) going down from midbrain to pons to medulla. CN XI is an exception, as its nucleus is in the cervical cord. Motor nuclei are medial in the brain stem, sensory are lateral. Although most CN innervate the ipsilateral side, CN IV loops around and innervates the contralateral superior oblique.

Hope that helps a little.
