Intracranial Extracerebral Blood Vessels
- Molecular classification
- Blood Vessels, Arteries, Veins
01
Overview
Intracranial extracerebral blood vessels are the arteries and veins located within the cranial cavity but outside the brain parenchyma. These vessels are responsible for delivering oxygen and nutrients to the brain and removing waste products. They play a crucial role in maintaining the blood-brain barrier and regulating cerebral blood flow. Diseases affecting these vessels include aneurysms, stenosis, vascular malformations, and stroke. Their health is vital for maintaining proper neuronal environment through regulated perfusion as well as participation in complex fluid exchange systems unique to central nervous system physiology.
