Where is l12 in the spine

The twelfth thoracic vertebra is the largest of the thoracic vertebrae. The first of the transition vertebrae, the T9 vertebrae location is between the T8 and T10 vertebrae. It rests between the T10 and T12 vertebrae. The T12 vertebra sits right above the lumbar spinal column. It is the largest and most inferior of the thoracic spinal vertebrae. The T12 vertebrae location is between the T11 vertebra and the first lumbar vertebra, L1, in the trunk region. Since the T9 vertebra directly communicates with the adrenal glands, damage to this vertebra may produce severe symptoms in the kidney area.

Any damage to the thoracic vertebrae causes moderate to severe back pain that is exacerbated by movement. An injury to the T10 vertebra will likely result in a limited or complete loss of use of the lower abdomen muscles, as well as the buttocks, legs, and feet.

A minor injury will result in minor symptoms such as weakness, numbness, as well as partial or complete lack of muscle control over only one side of the body. Severe damage to this vertebra can result in complete paraplegia. A T11 injury will demonstrate itself by severe back and leg pain.

If the nerves in the T11 vertebrae are damaged, common symptoms include weakness and numbness in these areas. Like the other transition vertebrae, T12 vertebra pain symptoms involve severe to moderate back pain depending on the seriousness of the injury. Limited function of the legs can result as well, though this may be limited to only one side of the body.

Although T9 - T12 are very similar, there are thoracic vertebrae differences. Each descending vertebrae is larger than the one before in order to support the weight of the above spinal column. Therefore, the T12 segment is larger than the previous T9 - T11 vertebrae. Additionally, each vertebrae protects spinal nerves that correspond to different areas.

For instance, T9 contains nerves that connect to the kidney area while T12 has nerves that affect the buttocks and lower abdomen muscles. The T9 - T12 are part of the twelve vertebrae that make up the thoracic section of the spinal column, which lies between the cervical and lumbar regions.

Although thoracic spinal cord injuries are severe, they are not as fatal as SCI higher up on the spinal cord. Thoracic spinal cord injuries may affect one or both sides of the body, and although the long-term prognosis is good, early treatment is still critical for the outcome. Here are some different spinal cord injury types that account for most thoracic vertebrae injuries. Thoracic vertebrae fractures are usually due to accidents with hard falls and physical trauma, or conditions such as osteoporosis.

This injury occurs when the vertebrae spine collapses in its weakened state due to pressure. Thoracic vertebrae fractures are also known as compression fractures since pressure causes the weakened thoracic vertebrae to collapse. This is explained in more detail on the next page.

The T12 vertebra is located in the spinal column of the thoracic or trunk region inferior to the T11 vertebra and superior to the first lumbar L1 vertebra. The vertebral arch of T12 is thicker and stronger than its counterparts in the other thoracic vertebrae and in many ways resembles the vertebral arches of the lumbar vertebrae.

A pair of strong pedicles extends posteriorly from the vertebral body to begin the arch. Each pedicle contains a smooth, oval-shaped articular facet that forms a joint with the 12th pair of ribs. Posterior to the pedicles are the transverse processes that extend laterally from the vertebral arch.
