| arteria vertebralis | <anatomy, artery> Paired arteries which supply the muscles of the neck, spinal cord and cerebellum. (27 Sep 1997) |
|---|---|
| canalis vertebralis | The canal that contains the spinal cord, spinal meninges, and related structures. It is formed by the vertebral foramina of successive vertebrae of the articulated vertebral column. Synonym: canalis vertebralis, spinal canal, tubus vertebralis. (05 Mar 2000) |
| venae columnae vertebralis | Includes the internal and external vertebral venous plexuses, the basivertebral veins, and the anterior and posterior spinal veins. Synonym: venae columnae vertebralis. (05 Mar 2000) |
| vena vertebralis | <anatomy, vein> A vein derived from tributaries (venae comitantes) which run through the foramina in the transverse processes of the first six cervical vertebrae and form a plexus around the vertebral artery; it empties as a single trunk into the brachiocephalic veins. Synonym: vena vertebralis. (05 Mar 2000) |
| vena vertebralis accessoria | <anatomy, vein> A vein that accompanies the vertebral vein but passes through the foramen of the transverse process of the seventh cervical vertebra and opens independently into the brachiocephalic vein. Synonym: vena vertebralis accessoria. (05 Mar 2000) |
| vena vertebralis anterior | <anatomy, vein> The small vein that accompanies the ascending cervical artery; it opens below into the vertebral vein. Synonym: vena vertebralis anterior. (05 Mar 2000) |
| regio vertebralis | The central region of the back, corresponding to the underlying vertebral column. Synonym: regio vertebralis. (05 Mar 2000) |
| chorda vertebralis | An obsolete term for notochord. (05 Mar 2000) |
| columna vertebralis | The series of vertebrae that extend from the cranium to the coccyx, providing support and forming a flexible bony case for the spinal cord. Synonym: columna vertebralis, backbone, dorsal spine, rachis, spina dorsalis, spina, spina, spinal column, spine, vertebrarium. (05 Mar 2000) |
| plexus venosus vertebralis | Any of four interconnected venous networks surrounding the vertebral column; anterior external vertebral venous plexus, the small system around the vertebral bodies; posterior external vertebral venous plexus, the extensive system around the vertebral processes; anterior internal vertebral venous plexus, the system running the length of the vertebral canal anterior to the dura; posterior internal vertebral venous plexus, the system running the length of the vertebral canal posterior to the dura; the latter two constitute the epidural venous plexus. Synonym: plexus venosus vertebralis, Batson's plexus, vertebral venous plexus. (05 Mar 2000) |
| plexus vertebralis | <anatomy, artery> A plexus of autonomic nerves on the vertebral artery derives from the subclavian plexus. Synonym: plexus vertebralis, vertebral plexus. (05 Mar 2000) |
| nervus vertebralis | <anatomy, nerve> A branch from the stellate ganglion that ascends along the vertebral artery to the level of the axis or atlas, giving branches to the cervical nerves and meninges. Synonym: nervus vertebralis. (05 Mar 2000) |
| incisura vertebralis | One of the two concavities above (superior) and below (inferior) the pedicle of a vertebra; the notches of two adjacent vertebrae (plus the intervertebral disc) form an intervertebral foramen. Synonym: incisura vertebralis, intervertebral notch. (05 Mar 2000) |
| theca vertebralis | Single-layered strong membrane, comparable to and continuous with (at foramen magnum) the meningeal layer of the intracranial dura mater of the brain. It does not (in contrast to the dura mater of brain) adhere to the enveloping bony structures (vertebrae) or their periosteum, being separated from the latter by a considerable space, the vertebral epidural space-a true space containing the internal vertebral venous plexus embedded in a matrix of epidural fat. Synonym: dura mater spinalis, endorrhachis, theca vertebralis. (05 Mar 2000) |
| tubus vertebralis | The canal that contains the spinal cord, spinal meninges, and related structures. It is formed by the vertebral foramina of successive vertebrae of the articulated vertebral column. Synonym: canalis vertebralis, spinal canal, tubus vertebralis. (05 Mar 2000) |
