Cerebral arteries are blood vessels that supply oxygen-rich blood to the brain. They branch off from the internal carotid arteries and the vertebral arteries, ensuring that different regions of the brain receive the necessary nutrients and oxygen for proper function. These arteries play a crucial role in maintaining brain health. If a cerebral artery becomes blocked or narrowed, it can lead to serious conditions such as a stroke or transient ischemic attack (TIA), which can affect cognitive abilities and overall brain function.
