The Human Brain : From Neurone to Nervous System

CEREBRAL ARTERIES AND VEINS


  1. The rate of metabolism of the brain is amongst the highest of all organs in the body. Aerobic metabolism provides for all the essential brain functions, and a good supply of oxygen is essential for normal brain function. The arterial blood supply to the brain is the source of oxygen, and if the blood supply is compromised (ischaemia), then brain tissue can be destroyed.

  2. This tutorial considers the arterial supply and venous drainage of the brain. In addition factors that complicate the issue such as raised intracranial pressure and haemorrhage are considered briefly.

  3. Key Words: Cerebral arteries and veins. Intracranial haematomas and haemorrhages.
