Aivovaltimot

Aivovaltimot, also known as cerebral arteries, are a network of blood vessels that supply oxygenated blood to the brain. These arteries are crucial for the proper functioning of the brain, as even a brief interruption of blood flow can lead to severe and irreversible damage.

The major cerebral arteries include the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery. These arteries arise from the internal carotid arteries and the vertebral arteries, which in turn branch from the aorta. The anterior and middle cerebral arteries primarily supply the frontal and lateral parts of the brain, while the posterior cerebral artery serves the occipital lobe and parts of the temporal lobe.

A complex network of smaller arteries and arterioles further distributes blood throughout the brain tissue. This intricate vascular system ensures that all areas of the brain receive a continuous supply of oxygen and nutrients. The brain's high metabolic rate demands a constant blood flow, and any disruption can quickly lead to neurological deficits.

Conditions affecting the aivovaltimot, such as atherosclerosis (hardening of the arteries), aneurysms (weakening and bulging of artery walls), or embolisms (blockages by blood clots), can lead to serious health problems like stroke. A stroke occurs when blood flow to a part of the brain is interrupted, causing brain cells to die. Understanding the anatomy and function of the aivovaltimot is fundamental to comprehending various neurological disorders and developing effective treatments.
