CEREBROVASCULAR DISORDERS The term cerebrovascular disorder can be taken to mean ‘any disruption of brain functioning arising from some pathological condition related to the blood vessels, which produces an array of disorders of great complexity’ (Walsh, 1987). Since all cerebrovascular disorders originate due to impairment in the blood supply within the brain, it is important for one to understand the setup and functions of the arteries that are involved in this process. 1. ARTERIES AND BLOOD FLOW OF THE BRAIN: Since the central nervous system is one of the most active tissues in the body, it requires a rich supply of oxygen and glucose. One realizes the importance of understanding the circulation system when you consider the fact that impairment to blood supplies is the leading cause of lesions in the central nervous system. It is also important to have knowledge of the distribution of blood in the brain via the various branches, since any interruption in the blood supply is often associated with characteristic neuropsychological signs and symptoms. Blood transports oxygen and other nutrients necessary for the health of neurons, so a constant flow of blood to the brain must be maintained. 1.1 SUBCLAVIAN ARTERY: The main artery of the body is called the aorta. It supplies blood to all parts of the body with the exception of the lungs. The aorta ascends from the heart and forms an arch, from which arise two subclavian arteries. Each subclavian has two main branches, the common carotid and the vertebral. Both of these carry blood to the brain. Each common carotid divides into an external carotid artery, which supplies blood to the face and an internal carotid artery, which supplies the brain with blood. The external carotid is a fairly straight artery, so it is not prone to blockages due to the build up of
