MIDDLE CEREBRAL ARTERIES Meaning and
Definition
-
Middle cerebral arteries (MCA) are major blood vessels located in the brain that play a crucial role in supplying oxygenated blood to various regions of the brain's outer surface, including areas responsible for movement, sensation, and language. The MCA is one of the paired cerebral arteries, along with the anterior cerebral arteries and posterior cerebral arteries, that form part of the Circle of Willis, the network of blood vessels that provide collateral circulation to the brain.
These arteries arise from the internal carotid arteries and their main branches branch extensively over the lateral hemispheres of the brain. The left and right MCAs are responsible for the blood supply to the majority of the lateral cortex, which encompasses parts of the frontal, temporal, and parietal lobes. Each MCA distributes blood to specific regions of the brain, with the left MCA mainly supplying the dominant hemisphere that controls language, while the right MCA supplies the non-dominant hemisphere that plays a role in spatial awareness and recognition.
The MCA's blood supply is vital for maintaining brain function, as any disruption, such as an MCA stroke caused by a blood clot or blockage, can lead to severe neurological symptoms and potential brain damage. Due to their anatomical positioning and important role, researchers and clinicians closely study the middle cerebral arteries to understand various pathologies, diagnostic techniques, and treatment options related to brain disorders and vascular diseases.
