What is performed to restore blood flow through narrowed vessels?
cerebral angioplast and stent
How may moyamoya disease lead to cerebral hemorrhaging?
Cerebral hemorrhage occurs as a result of breakdown of the coexisting blood vessels that formed earlier in life due to stenosis or occlusion of the ICA
How does carbon dioxide affect cerebral artery?
CO2 causes vasodilation of the cerebral artery. The mechanism is pressumed to be due to direct effect of CO2 on the wall of the blood vessels. Anecdotal/clinical evidence: In emergency head injury, raised intracranial pressure can be treated by hyperventilating the patient. Hyperventilation reduces the PaCO2 in the blood. This causes vasoconstriction of the cerebral vessels and reduces ICP almost immediately.
Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
What two blood vessels are connected by anterior communicating artery?

How does oxygen get to your brain?
Simplified answer: Oxygenated blood reaches the brain via the Internal Cerebral Artery and the Vertebral Arteries. These vessels have many branches (Posterior, Middle, and Anterior Cerebral Arteries) going to different parts of the brain. Once oxygen reaches the capillary beds of these vessels it diffuses through the capillary walls to supply brain tissue.
Why raised intracranial pressure in Respiratory acidosis?
Widespread vasodilation results from hypercapnia leading to the warm peripheries and plethora that are also well documented. Cerebral vessels are not spared and this vasodilation also results in cerebral oedema increasing ICP.
