The parietal anterior artery (a. parietalis anterior) is one of the branches of the internal carotid artery (a. carotis interna) and provides blood supply to the upper part of the frontal lobe of the brain.
The parietal anterior artery runs along the superior edge of the frontal bone and enters the skull through a bony gap called the supramastoid foramen. It then travels to the upper part of the frontal lobe, where it branches into several small arteries that supply blood to this area of the brain.
Disruption of the blood supply to the branches of the parietal anterior artery can lead to various neurological disorders, such as impaired motor and sensory functions, as well as cognitive impairment, such as impaired memory and concentration.
In addition, the parietal anterior artery can also be used as a source for microsurgical transplants, for example, to restore blood supply to other areas of the brain.
It should be noted that the parietal anterior artery is part of the complex circulatory system of the brain, and its disruption may be associated with broader diseases such as strokes, brain tumors and other pathologies.
Thus, the parietal anterior artery plays an important role in the blood supply to the brain, and its disruption can have serious consequences. However, thanks to modern diagnostic and treatment methods, many diseases associated with this artery can be successfully diagnosed and treated.
