| STA-MCA | Superficial temporal artery - middle cerebral artery |
| STA-MCA | Superficial temporal artery to middle cerebral artery |
| ACA | Anterior Cerebral Artery |
| AChA | Anterior choroidal artery |
| costal groove for subclavian artery | <anatomy, artery> A groove immediately posterior to the scalene tubercle on the upper surface of the first rib across which the subclavian artery passes. Synonym: sulcus costae arteriae subclaviae. (05 Mar 2000) |
|---|---|
| accessory vertebral vein | <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) |
| anterior vertebral scalloping | <radiology> Hodgkin's disease, aortic aneurysm, tuberculosis of the spine (12 Dec 1998) |
| anterior vertebral vein | <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) |
| veins of vertebral column | 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) |
| vertebral | <anatomy> Of or pertaining to a vertebra. Origin: L. Vertebralis (18 Nov 1997) |
| vertebral arch | The posterior projection from the body of a vertebra that encloses the vertebral foramen; it consists of paired pedicles and laminae; the spinous, transverse, and articular processes arise from the arch. In aggregate, the venous arches-and the ligamenta flava that unite them-form the posterior wall of the vertebral (spinal) canal. Synonym: arcus vertebrae, neural arch. (05 Mar 2000) |
| vertebral-basilar system | The arterial complex comprising the two vertebral arteries joining to form the basilar artery, and their immediate branches. (05 Mar 2000) |
| vertebral border of scapula | The edge of the scapula closest to the vertebral column, extending from superior angle to inferior angle. Synonym: margo medialis scapulae, vertebral border of scapula. (05 Mar 2000) |
| vertebral canal | 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) |
| vertebral column | 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) |
| vertebral epidural space | 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) |
| vertebral foramen | The foramen formed by the union of the vertebral arch with the body; in the articulated vertebral column, the vertebral foramen collectively form the vertebral column. Synonym: foramen vertebrale. (05 Mar 2000) |
| vertebral formula | A formula indicating the number of vertebrae in each segment of the spinal column; for man it is C. 7, T. 12, L. 5, S. 5, Co. 4 = 33, the letters standing for cervical, thoracic, lumbar, sacral, and coccygeal. (05 Mar 2000) |
| vertebral fusion | A procedure that involves fusing together two or more vertebrae in the spine using either bone grafts or metal rods (Harrington rods). This procedure may be used to correct kyphosis or scoliosis. It is also used in those who require spine stabilisation due to vertebral damage from ruptures discs, fractures, osteomyelitis, osteoarthritis or tumour. (27 Sep 1997) |
