Summary
The hypoglossal nerve is a pure motor nerve with its nucleus located in the medial caudal medulla. The nerve exits from the medullary portion of the brainstem (bottom third) and travels through the hypoglossal canal (a hole that shares my name). It is commonly tested on neurological exam by asking patients to stick out their tongue and looking for deviation. Thus, if you are trying to catch a falling snowflake on your tongue, a lesion of CN XII will cause ipsilateral tongue deviation.
