The human spine is comprised of 24 individual vertebrae. The thoracic vertebra consists of 12 vertebrae, located below the cervical vertebra, which are underneath the skull and the lumbar vertebrae at the base of the spine. The second thoracic vertebra, or T2, is located directly below the first vertebrae. It is slightly larger than the first vertebrae, but smaller than the third vertebrae. The second thoracic vertebrae contain faceted sides that allow the vertebrae to press up against the ribs. The thoracic spinal nerve 2 moves underneath the vertebra. The spinal nerve consists of different nerves moving along the spinal column. The nerves control sensory signals and motor signals from the spinal column to the body, making the body react to the movement of the spine. Injuries to the spine typically concern the lower vertebrae, but it is possible for a patient to sustain injury to the T2. Doctors designate the injury based on the thoracic vertebrae number, with a T2 injury referring to an injury involving the second thoracic vertebrae.
