an·te·ri·or ce·re·bral ar·ter·y

[TA]
one of the two terminal branches (with middle cerebral artery) of the internal carotid; it passes anteriorly, loops around the genu of the corpus callosum, and then passes posteriorly in the longitudinal fissure along with its fellow of the opposite side, the two being joined by the anterior communicating artery [TA]. For descriptive purposes, it is divided into two parts: 1) the precommunicating part [TA] (A1 segment in clinical terminology), which gives rise to the anteromedial central arteries [TA], consisting of proximal medial striate arteries [TA], the supraoptic artery [TA], anterior perforating arteries [TA], and preoptic arteries [TA] and 2) a postcommunical part [TA] (A2 segment), which gives rise to a distal medial striate artery [TA], medial frontobasal artery [TA], polar frontal artery [TA], and two large terminal branches: the pericallosal artery [TA] and the callosomarginal artery [TA]. The latter two have branches that serve specific regions of the cortex.
Synonym(s): arteria cerebri anterior [TA]

an·te·ri·or ce·re·bral ar·te·ry

(an-tēr'ē-ŏr ser'ĕ-brăl ahr'tĕr-ē) [TA]
One of two terminal branches (with middle cerebral artery) of internal carotid; passes anteriorly, loops around genu of corpus callosum, then passes posteriorly in interhemispheric fissure along with its fellow of opposite side, the two being joined by the anterior communicating artery.
Synonym(s): arteria cerebri anterior.

anterior cerebral artery

An artery that supplies blood to the medial side of the cerebral hemisphere and the corpus callosum; it is part of the circle of Willis, and it branches from the internal carotid artery at the base of the brain. The anterior cerebral artery anastomoses with the contralateral anterior cerebral artery via the anterior communicating artery.
