cerebralartärer
Cerebralartärer refers to the arteries that supply blood to the brain. These are critical for providing oxygen and nutrients essential for brain function. The primary cerebral arteries include the internal carotid arteries and the vertebral arteries. The internal carotid arteries ascend through the neck and enter the skull, where they branch into the anterior cerebral artery and the middle cerebral artery. The vertebral arteries also ascend through the neck, pass through the skull, and merge to form the basilar artery. The basilar artery then bifurcates into the posterior cerebral arteries. These arteries are interconnected by the Circle of Willis, an important arterial anastomosis located at the base of the brain. This structure helps to ensure continuous blood flow to the brain, even if one of the major arteries is partially blocked. Diseases affecting cerebral arteries, such as atherosclerosis, can lead to stroke, a condition characterized by sudden loss of brain function due to an interruption of blood supply. Other conditions impacting cerebral arteries include aneurysms, which are bulges in the artery wall, and arteriovenous malformations, which are abnormal connections between arteries and veins. Medical imaging techniques like angiography are used to visualize and diagnose conditions affecting these vital blood vessels.
