The vertebral artery is a major artery of the neck that passes through the cervical vertebrae. There are two vertebral arteries, one on each side, and each branches off from the subclavian artery. They merge to form the single basilar artery at the base of the brain.
Each cervical vertebra consists of a thin ring of bone, or vertebral arch, surrounding the vertebral and transverse foramina. The vertebral foramen is a large opening in the center of the vertebra that provides space for the spinal cord and its meninges as they pass through the neck. Flanking the vertebral foramen on each side are the much smaller transverse foramina. The transverse foramina surround the vertebral arteries and veins, which, along with the carotid arteries and jugular veins, have the vital job of carrying blood to and from the brain.
