Cranial blood vessels are the network of arteries and veins that supply blood to the brain and surrounding structures. The major arteries include the internal carotid arteries and the vertebral arteries, which branch off to provide oxygen-rich blood. These vessels are crucial for maintaining brain function and overall health. Veins in the cranial region, such as the jugular veins, help return deoxygenated blood back to the heart. The cerebral venous sinuses also play a role in draining blood from the brain. Proper functioning of these blood vessels is essential for preventing conditions like stroke and other neurological disorders.
