The vertebral arteries usually arise from the posterosuperior aspect of the central subclavian arteries on each side of the body, [2] then enter deep to the transverse process at the level of the 6th cervical vertebrae (C6), [1] or occasionally (in 7.5% of cases) at the level of C7.
This is a list of arteries of the human body. The aorta; ... Vertebral artery: Int. thoracic a: Thyrocervical trunk: Costocervical trunk: Dorsal scapular artery (mostly)
Vertebral arteries: These smaller arteries branch from the subclavian arteries which primarily supply the shoulders, lateral chest, and arms. Within the cranium the two vertebral arteries fuse into the basilar artery .
The basilar artery (U.K.: / ˈ b æ z. ɪ. l ə /; [1] [2] U.S.: / ˈ b æ s. ə. l ər / [3]) is one of the arteries that supplies the brain with oxygen-rich blood.. The two vertebral arteries and the basilar artery are known as the vertebral basilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of ...

After cardiologist Danielle Belardo, MD, saw a young patient suffering a stroke post-neck manipulation, she spoke up. Here's what MDs want you to know.
The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle. The right and left posterior cerebral arteries arise from the basilar artery, which is formed by the left and right vertebral arteries. The vertebral arteries arise from the subclavian arteries.
Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot , thickening the artery wall and often impeding blood flow.
