How many vertebrae are in the thoracic spine?

The thoracic spine consists of 12 vertebrae, which is a key aspect of human anatomy. These vertebrae are labeled T1 through T12 and are located in the middle portion of the vertebral column, situated between the cervical spine (neck region) and the lumbar spine (lower back). The structure of the thoracic spine is important as it provides attachment points for the ribs and supports the thoracic cavity, which houses vital organs, including the heart and lungs.

Moreover, the thoracic vertebrae have unique features compared to those in other regions of the spine, such as facets for rib articulation and a larger body to support the additional weight of the upper body. Understanding the anatomy and function of the thoracic spine is crucial for interventions related to spinal health and is foundational knowledge for physical therapy practice.
