The paired vertebral arteries are the first and largest branches of the subclavian arteries. They arise from the subclavian arteries, usually ascend through the transverse processes of the upper six cervical vertebrae, pass behind the lateral masses of t
The vertebral artery is tightly anchored at the dura mater of the foramen magnum along its course through it; this junction is called the distal dural ring. Along its course, the vertebral artery V3 segment is surrounded by a venous plexus inside a periosteal sheath. The relative positions of...
The intracranial segment of the vertebral artery (VA) is the unique part of the artery where the two VAs join to form a single vascular channel, viz. the basilar artery. In addition to this typical description, anatomical variations have been described; the presence of anatomical variation has ...
