Thoracic Vertebrae Numbers

The thoracic spine is comprised of 12 vertebrae labeled T1 through T12. The top thoracic vertebra, T1, connects with C7 in the cervical spine above while the bottom thoracic vertebra, T12, connects with L1 in the lumbar spine below. In addition to being connected to adjacent vertebrae, the thoracic vertebrae are also connected to ribs.

Distinguishing features. The body of a thoracic vertebra is somewhat “heart-shaped,” and is larger than the cervical but smaller than the lumbar vertebrae in size. The body also has small, smooth, and somewhat concave costal facets for the attachment of the ribs. Ribs are generally inserted between two vertebrae,…

[edit on Wikidata] In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae.
