What is the circle of Willis?
First thing’s first: what is the circle of Willis? Simply(ish) put, the circle of Willis is a circulatory anastomosis supplying blood to the brain and neighboring structures. These arteries are located at the base of the brain, close to the optic chiasm.
Circle of Willis arteries
The circle of Willis, also known as the cerebral arterial circle, is formed by anterior and posterior arterial pathways.
The arteries of the circle of Willis include:
- One anterior communicating artery
- Two anterior cerebral arteries (left and right)
- Two internal carotid arteries (left and right)
- Two posterior communicating arteries (left and right)
- Two posterior cerebral arteries (left and right)
- One basilar artery
As such a tricky topic, it might be beneficial to try drawing the structures of the circle of Willis to help consolidate your memory. Here's the ultimate drawing reference.
Next we’re going to look at how you can continue learning and building upon your knowledge with some circle of Willis Quizzes. But first, you might like to watch our videos on the arteries of the brain. This will give you a bit more detail about the arteries comprising the circle of Willis. You can even follow along with the transcript!
Labeled and unlabeled diagrams
One of the best ways to get familiar with the anatomy of a structure is to study a labeled diagram. Have a look at the circle of Willis diagram below, which lists the main arteries.
Once you think you’ve memorized the name and location of each artery on the diagram, try labeling them for yourself using the free circle of Willis (unlabeled) PDF below. If you want to make some notes as you study, you can download the labeled circle of Willis diagram, too.
