What is the total number of vertebrae found in the thoracic spine?

The thoracic spine consists of 12 vertebrae, which are designated as T1 through T12. These vertebrae play a crucial role in forming the upper and middle back and serve as an attachment point for the ribs, contributing to the structure of the rib cage. This anatomical feature provides both stability and protection for vital organs, such as the heart and lungs. The intervertebral discs between these vertebrae allow for movement and flexibility in the spine while also absorbing shock during physical activities. Understanding the number of vertebrae in the thoracic spine is important for various clinical applications, as well as for diagnosing and treating spinal disorders.
