Vasculature of the Cervical Spine
This exhibit depicts the lateral, sagittal, and superior vasculature of the cervical spine. The vertebral artery can be seen traveling superiorly through the transverse foramina from C6 to C1. It then passes through the foramen magnum at the base of the skull to supply the brain. Radicular arteries branch from the vertebral artery at each cervical level and pierce the dura to supply each nerve root. Once inside the dura, the radicular arteries enter the spinal canal to join with the ventral and dorsal spinal arteries supplying the spinal cord.
