posterior cerebral artery in dogs

The posterior cerebral artery (PCA) is one of a pair of blood vessels that supplies oxygenated blood to the posterior aspect of the brain in human anatomy]. It arises near the intersection of the posterior communicating artery and the basilar artery and connects with the ipsilateral middle cerebral artery (MCA) and internal carotid artery via the posterior communicating artery (PCommA). [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the posterior cerebral artery is

The posterior cerebral artery (PCA) is one of a pair of blood vessels that supplies oxygenated blood to the posterior aspect of the brain in human anatomy]. It arises near the intersection of the posterior communicating artery and the basilar artery and connects with the ipsilateral middle cerebral artery (MCA) and internal carotid artery via the posterior communicating artery (PCommA). [WP,unvetted]. The atlas records it as a artery at the organ scale in the dog.

Where the posterior cerebral artery is

It sits in the head, within the cardiovascular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the posterior cerebral artery connects to

The atlas records 7 typed relationships for it, across 3 kinds of connection. part of anatomical entity and basilar artery.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the posterior cerebral artery. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as arteria cerebri posterior. Searching any of those names reaches this page.
