There are 5 sacral vertebral bones. They are represented by the symbols S1 through S5 and are situated between the lumbar vertebrae and the coccyx (the lowest segment of the vertebral column). The sacral vertebrae are normally fused to form the sacrum.
- Vertebrae, thoracic
The 12 thoracic vertebrae are situated between the cervical (neck) vertebrae and the lumbar vertebrae. The thoracic vertebrae are represented by the symbols T1 through T12. The thoracic vertebrae provide attachment for the ribs and make up part of the back of the thorax (the chest).
- Vertebral arch
A circle of bone around the canal through which the spinal cord passes. A vertebral arch is composed of a floor at the back of the vertebra, walls (the pedicles), and a roof where two laminae join.
- Vertebral artery
One of two key arteries located in the back of the neck that carry blood from the heart to the brain, spine, and neck muscles.
- Vertebral column
small, rudimentary vertebrae that fuse together. Also known as the spinal column.
- Vertebral compression fracture
A fracture that collapses a spinal vertebra as a result of the compression of bone, leading to collapse of the vertebrae much like a sponge collapses under the pressure of one’s hand. Although they may occur without pain, such vertebral fractures often cause a severe, band-like pain that radiates from the spine around both sides […]
