Neuroanatomy: circle of Willis: practice question

The best answer is A, Anterior communicating artery. The anterior communicating artery joins the left and right anterior cerebral arteries.

Posterior communicating artery links internal carotid to posterior cerebral circulation.

Middle cerebral artery is a major internal carotid branch but not the connecting artery.

Basilar artery is formed by the vertebral arteries.

It tests Neuroanatomy: circle of Willis in Anatomy. Aneurysms here can affect optic pathways and anterior cerebral circulation.

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

Learn every nerve by its route, its muscles and what a lesion looks like at the bedside. That one habit answers a large share of questions. Then use the flashcards and the other Anatomy questions on this site to test what stuck.

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
