What are the anterior brain arteries?

Front brain arteries (ACA) are two arteries of the brain that provide oxygen the most superior medial parietal lobes and the central part of the frontal lobes. The playgrounds are connected by the front communicating arteries. They are a vital part of the proper function of the brain.

It is located on the upper part of the brain, the anterior brain arteries operate the outer surface of the brain hemisphere. This area consists of a long lane that extends from the frontal lobe to the back of the brain. In addition to the parietal and frontal lobes, the olfactory bulb and the tract, the front area of ​​the inner capsule and the basal ganglia and the part of the side surface of the parietal and frontal lobe, which sits on the basis of the central Fissure. A5. The A1 segment base is associated with the internal carotid artery and stretches to the front communication artery (COMM). Then A2 ranges from communication to pericallososis and callosomarginal artery. Orbitofrontal and queue arteries also range from the A2 segment.

segment A3 is another name for sentencesEV pericalloscal arteries of the anterior brain arteries. This segment consists of precathy and internal parietal arteries. Small branches that reach from the front brain arteries are A4 and A5 segments. They are also known as Callosl arteries.

Front brain arteries are part of the Willis circle, a circle of arteries on the brain that provides a continuous blood flow in the brain. This circle plays a key factor in preventing strokes. The anterior brain arteries are associated with an anterior communicating, internal carotid, rear brain and rear -communicating artery circle.

Incorrect functioning of the anterior brain arteries can cause dramatic changes in the body. Most problems arise from bilateral occlusion on the arteries' stems. This can cause conditions from urinary incontinence and abulic and motoring aphasia to paraplegia on the lower limbs. It can also affect the frontal lobe and results in contralateral grip of reflex or change of personality.
