Editing Midbrain (section)

==Blood supply==
The midbrain is supplied by the following [[arteries]]:

* The tectum is supplied by the [[superior cerebellar artery]].
* The central part of the tegmentum is supplied by the paramedian branches of the [[basilar artery]].
* The lateral part of the midbrain is supplied by the [[posterior cerebral artery]].

[[Venous blood]] from the midbrain is mostly drained into the [[basal vein]] as it passes around the peduncle. Some venous blood from the colliculi drains to the [[great cerebral vein]].<ref>{{Cite book |last=Sinnatamby |first=Chummy S. |title=Last's Anatomy |vauthors= |publisher= |year=2011 |isbn=978-0-7295-3752-0 |edition=12th |pages=478}}</ref>
