Which artery is formed by the joining of the vertebral arteries?

• A. Middle cerebral
• B. Basilar
• C. Common carotid
• D. Posterior cerebral

Answer: (B)

The correct response is indeed the basilar artery. The basilar artery is formed by the union of the two vertebral arteries, which travel along the spinal column and enter the skull, ultimately joining at the base of the brain. This important vessel supplies blood to the posterior part of the brain, including the brainstem and cerebellum, and is crucial for various brain functions. The vertebral arteries themselves arise from the subclavian arteries and ascend through the foramina of the cervical vertebrae. Upon entering the cranial cavity, they come together to form the basilar artery at the level of the pons, which provides essential vascular supply to the brain regions that support life-sustaining activities and motor coordination.
