Cerebral circulation ensures continuous blood supply to the brain, which consumes nearly 20% of the body’s oxygen. In this video, we cover:
✅ Arterial supply: Internal carotid & vertebral arteries, Circle of Willis
✅ Venous drainage via dural venous sinuses & jugular veins
✅ Blood flow & oxygen consumption in the brain
✅ Measurement techniques (Kety’s method, PET, MRI)
✅ Regulation of cerebral blood flow:
Metabolic factors (CO₂, H⁺, lactate, adenosine)
Autoregulation (60–140 mmHg range)
Intracranial pressure & Monro–Kellie doctrine
Neural regulation via sympathetic system
