Thoracic Spine


Updated May 22, 2005

Definition: The thoracic spine is the area of the vertebral column commonly refered to as the mid and upper back. The thoracic spine occupies the same level as the ribcage.

The thoracic spine is made up of 12 vertebrae, refered to by 'T', appended with an identifying number. The number indicates the level of the spine in which the particular vertebra is located.


  • The 1st thoracic vertebra is called T1 or T-1. The first rib begins at the level of T-1.
  • The 7th thoracic vertebra is called T7, or T-7.

    The curve of the cervical spine is a lordosis.

  • Also Known As: T-Spine
    The first rib begins at the level of T-1.
    T-12 sits on top of the first lumbar vertebra (known as L-1), and is the last thoracic vertebra.
