Flow Chart Blood Supply Of Brain Arterial Supply to the Brain There are two paired arteries which are responsible for the blood supply to the brain the vertebral arteries and the internal carotid arteries These arteries arise in the neck and ascend to the cranium
The document summarizes the arterial blood supply and venous drainage of the brain It discusses the two main sources of arterial blood the internal carotid and vertebral arteries It describes the branches of these arteries and their territories It also discusses the clinical consequences of occlusions in different arteries The The brain receives its arterial blood supply from the internal carotid arteries and vertebral arteries The internal carotid artery enters the cranium and gives off branches including the anterior cerebral artery and middle cerebral artery The vertebral arteries join to form the basilar artery which splits into the posterior cerebral arteries

Cerebral circulation is the movement of blood through a network of cerebral arteries and veins supplying the brain The rate of cerebral blood flow in an adult human is typically 750 milliliters per minute or about 15 of cardiac output Arteries deliver oxygenated blood glucose and other nutrients to the brain The normal average Cerebral blood flow is 50 ml 100gm min Two major sources of arterial blood provide this perfusion Posterior or vertebrobasilar circulation originates in vertebral arteries It is formed at the base of the brain in the intereduncular fossa C4from sup
The vertebral arteries and their major branches supply blood to the spinal cord brainstem and cerebellum and a significant part of the posterior cerebral hemispheres usually the occipital and inferior temporal lobes An overview of the arterial blood supply to the brain including the anterior and posterior cerebral circulation in addition to the Circle of Willis

Every time the heart beats arteries carry 20 to 25 of the blood to the brain The blood flow to the brain is vital to its function since it is particularly sensitive to oxygen starvation When an area of the brain is cut off from blood flow a stroke can result Owing to the high oxygen and nutrient demand of the organ it is supplied by two arterial systems The posterior circuit is supplied by the vertebrobasilar system The focus of this article will be to discuss the major arteries that supply the brain
The brain derives its arterial supply from the paired carotid and vertebral arteries Every minute about 600 700 ml of blood flow through the carotid arteries and their branches while about 100 200 ml flow through the vertebral basilar system We will review the blood supply some of the mechanisms of flow rate and how they might change in the brain The blood flow in the cerebrum of humans is essential for survival Regulation of cerebral blood flow is vital because it allows the brain to get its nutrients and oxygen even when the blood pressure in the body changes
