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. Sometimes this vessel is wanting, the two arteries joining together to form a single trunk, which afterward divides; or it may be wholly, or partially, divided into two. Its length averages about 4 mm, but varies greatly. It gives off some of the anteromedial ganglionic vessels, but these are principally derived from the anterior cerebral artery.
It is part of the cerebral arterial circle, also known as the circle of Willis.

Famous quotes containing the word anterior:
“But now moments surround us
Like a crowd, some inquisitive faces, some hostile ones,
Some enigmatic or turned away to an anterior form of time
Given once and for all. The jetstream inscribes a final flourish
That melts as it stays.”
—John Ashbery (b. 1927)
