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 […]
- Vertebral rib
The lower five ribs do not directly connect to the sternum and are known as false ribs. The upper three false ribs connect to the costal cartilages of the ribs just above them. The last two false ribs, however, usually have no ventral attachment (no anchor at all in front) and are called vertebral, fluctuating, […]
