The three pairs of arteries are linked via the anterior communicating artery and the posterior communicating arteries.

The anterior and posterior cerebral circulations are interconnected via bilateral posterior communicating arteries.

The posterior communicating arteries (PCoA).

In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis.

The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems.

The left and right MCAs rise from trifurcations of the internal carotid arteries and thus are connected to the anterior cerebral arteries and the posterior communicating arteries, which connect to the posterior cerebral arteries.

In circulatory anastomoses, many arteries naturally anastomose with each other, for example the inferior epigastric artery and superior epigastric artery, or the anterior and/or posterior communicating arteries in the Circle of Willis in the brain.

In the circle of Willis so-called communicating arteries exist between the front (anterior) and back (posterior) parts of the circle of Willis, as well as between the left and right side of the circle of Willis.

The anterior optic nerve is supplied by the short posterior ciliary artery and choroidal circulation, while the retrobulbar optic nerve is supplied intraorbitally by a pial plexus, which arises from the ophthalmic artery, internal carotid artery, anterior cerebral artery, and anterior communicating arteries.

Each posterior communicating artery connects the three cerebral arteries of the same side.

Communicating artery is a synonym for this term.

The origin of the posterior communicating artery.

The left and right anterior cerebral arteries are connected by the anterior communicating artery.

Posterior communicating artery, a blood vessel in the brain often referred to as the 'p-com'

If stroke occurs prior to the anterior communicating artery it is usually well tolerated secondary to collateral circulation.

Posterior communicating artery (left and right)

The anterior communicating artery.

One common cause of basal forebrain damage is aneurysm of the anterior communicating artery.

Communicating artery may refer to:

The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side.

The posterior cerebral artery and the posterior communicating artery are within the circle of Willis.

The anterior cerebral artery and the anterior communicating artery travel within this cistern.

In human anatomy, the anterior communicating artery is a blood vessel of the brain that connects the left and right anterior cerebral arteries.

The anterior communicating artery connects the two anterior cerebral arteries across the commencement of the longitudinal fissure.

The bleeding can involve the middle communicating artery or the posterior communicating artery.

The anterior and posterior cerebral circulations are interconnected via bilateral posterior communicating arteries.

In another variation the anterior communicating artery is a large vessel, such that a single internal carotid supplies both anterior cerebral arteries.

The posterior communicating arteries (PCoA).

About 20% of adults retain PCA origin from the posterior communicating artery, and in turn, the internal carotid arteries.

Anterior communicating artery: Connects both anterior cerebral arteries, within and along the floor of the cerebral vault.

A1: this segment originates from the internal carotid artery and extends to the anterior communicating artery (AComm).

Finally, rupture of the anterior or posterior communicating artery, subarachnoid hemorrhage, and encephalitis are also possible causes of confabulation.

Anterior communicating artery (arteria communicans anterior)

In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis.
