Cerebral arteries
Cerebral arteries
The cerebral arteries (/sɪˈriːbrəl ˈɑːrtəriːz/) are a group of arteries that provide oxygenated blood to the brain. The term originates from the Latin cerebrum, meaning brain, and the Greek arteria, meaning windpipe, which later came to denote arteries.
Anatomy
The cerebral arteries are divided into two main groups: the anterior cerebral arteries and the posterior cerebral arteries. These arteries arise from the internal carotid arteries and the vertebral arteries, respectively. They further divide into smaller branches, supplying all parts of the brain.
Function
The primary function of the cerebral arteries is to supply oxygenated blood to the brain. This is crucial for the brain's normal functioning, as it requires a constant supply of oxygen and nutrients to maintain its metabolic activities.
