With the anterior communicating artery, the posterior communicating arteries establish a system of collateral circulation in cerebral circulation. The arteries contribute to the blood supply of the optic tract. [1]: 465. The two posterior communicating arteries often differ in size. [1]: 472.

2023年11月3日 · The anterior communicating artery (AComm) is a short vessel that connects the left and right anterior cerebral arteries, forming the anterior border of the cerebral arterial circle of Willis. Together with the basilar artery, it is one of the two brain vessels that are not paired.

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.

2024年11月11日 · The posterior communicating artery (PCOM) is a part of a group of arteries in the brain known as the circle of Willis. The artery connects the internal carotid and the posterior cerebral arteries. Its role is to provide blood supply to the brain.

2023年11月3日 · The posterior communicating artery (PComm) is a branch of the internal carotid artery that participates in the cerebral arterial circle of Willis. The posterior communicating artery connects the internal carotid with the posterior cerebral arteries, thus connecting the anterior and posterior cerebral circulations.

2023年2月22日 · The anterior communicating artery (often abbreviated ACom or AComm) arises from the anterior cerebral artery and acts as an anastomosis between the left and right anterior cerebral circulation. Approximately 4 mm in length, it demarcates the junction between the A1 and A2 segments of the anterior cerebral artery. Branches. The anterior communicating artery …

2025年1月24日 · The anterior communicating artery (AComA) is a small yet vital artery within the brain’s circulatory system. It plays a key role in connecting the left and right anterior cerebral arteries (ACA), thus completing the anterior portion of the Circle of Willis .

The Anterior Communicating Artery (ACoA) is a blood vessel that connects the proximal anterior cerebral arteries near their entrance into the longitudinal fissure, playing a crucial role in supplying blood to the frontal and parietal lobes of the brain.

2023年7月28日 · The posterior communicating artery originates from the posterior aspect of the C7 (communicating) segment of the internal carotid artery and extends posteromedially to anastomose with the ipsilateral posterior cerebral artery and forms part of the circle of Willis.

2023年7月24日 · The anterior communicating artery (ACom A) is formed from a plexiform vascular network that coalesces in the midline and connects the two developing anterior cerebral arteries. The caudal ICA divisions anastomose with the dorsal longitudinal neural arteries.
