| block vertebrae | Congenitally fused and hypoplastic vertebral bodies which, on radiographs, give the appearance of a more or less solid bony mass. See: Klippel-Feil syndrome. (05 Mar 2000) |

| radix arcus vertebrae | The constricted portion of the arch on either side extending from the body to the lamina; bound intervertebral foramina superiorly and inferiorly. Synonym: pediculus arcus vertebrae, radix arcus vertebrae. (05 Mar 2000) |
| vertebrae | <anatomy> One of 23 bones (excluding the sacrum) in the cervical, thoracic and lumbar regions that comprise the spine. There are 7 cervical vertebrae, 12 thoracic and 5 lumbar vertebrae. The bottom of the spine is fused and forms the sacrum. (27 Sep 1997) |
