Fibres from the [[:wikt:ventral|ventral]] [[motor cortex]] travel with the corticospinal tract through the internal capsule, but terminate in a number of locations in the [[midbrain]] ([[cortico-mesencephalic tract]]), [[pons]] ([[Corticopontine tract]]), and [[medulla oblongata]] ([[cortico-bulbar tract]]).<ref name=YOUNG2007>{{cite book|last1=Young|first1=Paul A.|title=Basic clinical neuroscience|date=2007|publisher=Lippincott Williams & Wilkins|location=Philadelphia, Pa.|isbn=9780781753197|pages=69–70|edition=2nd|url=https://books.google.com/books?id=dCh_gIIUnEoC&q=corticobulbar+is+a+pyramidal+tract&pg=PA69|url-status=live|archive-url=https://web.archive.org/web/20170313215307/https://books.google.com/books?id=dCh_gIIUnEoC&pg=PA69&dq=corticobulbar+is+a+pyramidal+tract#v=onepage&q=corticobulbar%20is%20a%20pyramidal%20tract&f=false|archive-date=2017-03-13}}</ref> The [[upper motor neuron]]s of the corticobulbar tract synapse with interneurons or directly with the lower motor neurons located in the motor [[cranial nerve nuclei]], namely [[oculomotor]], [[trochlear motor neuron|trochlear]], motor nucleus of the [[trigeminal nerve]], [[abducens]], [[facial nerve]] and [[Accessory nerve|accessory]] and in the [[nucleus ambiguus]] to the [[hypoglossal]], [[vagus nerve|vagus]] and [[accessory nerve]]s.<ref name=YOUNG2007 /> These nuclei are supplied by nerves from both sides of the brain, with the exception of the parts of the facial nerve that control muscles of the lower face. These muscles are only innervated by nerves from the contralateral (opposite) side of the cortex.<ref name=YOUNG2007 />
