CAMRT Radiography Practice Exam

Which vessels supply blood to the brain?

1. Right internal carotid and left external carotid

2. Right vertebral artery and left external jugular vein

3. Right internal carotid, left internal carotid, right vertebral artery, and left vertebral artery

4. Right internal jugular and left internal jugular veins

The correct answer is: Right internal carotid, left internal carotid, right vertebral artery, and left vertebral artery

The vessels that supply blood to the brain are critical for maintaining its function, and understanding their anatomy is essential for anyone studying radiography or related medical fields. The correct choice includes both the internal carotid arteries and the vertebral arteries on both the right and left sides. The internal carotid arteries are major suppliers of blood to the anterior and middle parts of the brain. They branch into various arteries, including the anterior cerebral artery and middle cerebral artery, which are crucial for cerebral blood flow. The vertebral arteries, which converge to form the basilar artery, are significant for supplying the posterior areas of the brain, including the brainstem and cerebellum. The other options do not encompass all the necessary vessels. The choice that includes only the external carotid artery does not adequately contribute to cerebral blood supply; the external carotid primarily supplies blood to the face and neck. Similarly, choosing the jugular veins is incorrect because these vessels are responsible for draining blood from the brain rather than supplying it. The vertebral artery plays a crucial role in blood supply and is thus essential for inclusion in the correct answer. This integrated vascular supply from both internal carotid and vertebral arteries ensures that all parts of the brain receive the necessary oxygen and nutrients for
