Quizplus · Accepted Answer

The recurrent artery of Heubner, a branch of the anterior cerebral artery, primarily supplies the head of the caudate nucleus. The symptoms described, such as uncontrollable lip smacking, suggest a lesion in the basal ganglia, which includes the caudate nucleus. The head of the caudate is the most likely location for these symptoms given the artery involved.
