Arteria fossae Sylvii, commonly known as the artery of the fissure of Sylvius, is a major artery located within the human brain. It is specifically found in the cerebral hemispheres and is a branch of the middle cerebral artery (MCA).
The arteria fossae Sylvii arises from the MCA and runs along the lateral sulcus, also known as the Sylvian fissure. The Sylvian fissure is a prominent groove that separates the frontal and parietal lobes from the temporal lobe in both hemispheres of the brain. As the arteria fossae Sylvii courses within the fissure, it supplies blood to important areas of the brain, including the insula and parts of the frontal, parietal, and temporal lobes.
The artery of the fissure of Sylvius plays a critical role in the blood supply to these regions, providing essential oxygen and nutrients that enable proper brain function. It also participates in regulating cerebral blood flow and helps to maintain the overall perfusion of the brain.
In some cases, blockage or occlusion of the arteria fossae Sylvii can result in an ischemic stroke, which occurs when blood flow to a particular area of the brain is disrupted. This can lead to various neurological deficits, depending on the affected region.
Overall, the arteria fossae Sylvii is an important vascular structure in the brain, responsible for delivering blood to crucial areas that contribute to various cognitive and sensory functions. Its proper function is essential for maintaining the overall health and normal functioning of the human brain.
