Body was changed:

persistent hypoglossal artery is one of the persistent carotid-vertebrobasilar anastomoses. It is second in frequency to the trigeminal artery which is present approximately six times as often. 

It arises from the distal cervical ICA, usually between C1 and C3. After passing through an enlarged hypoglossal canal, it joins the basilar artery inferiorly. If large, the ipsilateral vertebral artery and PcomPCOM are often hypoplastic or absent. There is association an association with concurrent aneurysms.
