V2 (foraminal) travels alongside vertebral veins and nerves. The vertebral artery enters a space within the vertebrae called the transverse foramen at C6 and exits this space at the C2 cervical vertebra, the second-highest vertebra at the top of your spine, just below the skull.

2023年11月3日 · Arteries, veins, nerves and lymph nodes of the neck. The vertebral vein is a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. It arises at the level of the sixth cervical vertebra from a venous plexus that surrounds the vertebral artery and travels as far as the brachiocephalic veins.

The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas.

The vertebral arteries are major arteries of the neck. Typically, the vertebral arteries originate from the subclavian arteries. Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery.

2025年1月4日 · The vertebral arteries (VA) are paired arteries, each arising from the respective subclavian artery and ascending in the neck to supply the posterior fossa and occipital lobes, as well as provide segmental vertebral and spinal column blood supply.

2023年11月3日 · There are four segments of the vertebral artery, following its way through the neck; preforaminal, foraminal, extradural (atlantic), and intradural (intracranial) parts.

2024年3月31日 · There are two paired arteries which are responsible for the blood supply to the brain; the vertebral arteries, and the internal carotid arteries. These arteries arise in the neck, and ascend to the cranium.

2025年1月24日 · The vertebral artery runs along the vertebral column and is positioned close to the brainstem, playing a critical role in the blood supply to the posterior brain. Anatomy Origin. The vertebral artery arises from the subclavian artery on both the left and right sides of the body.

2025年1月23日 · The vertebral vein is a vein located within the cervical region of the neck, running alongside the vertebral artery and the cervical vertebrae. It originates from a venous plexus near the base of the skull and descends through the …

2021年11月1日 · Imaging of the vertebral arteries is part of a standard extra-cranial cerebrovascular ultrasound duplex scan. The vertebral arteries are smaller, located more distal from the transducer and partially “hidden” behind the bony structures of the vertebrae. Therefore they are more difficult to image.
