What is the correct number of thoracic vertebrae?

The human spine consists of various sections, and the thoracic vertebrae are specifically located in the middle portion of the spine between the cervical (neck) and lumbar (lower back) regions. There are a total of 12 thoracic vertebrae, each of which is numbered from T1 to T12. These vertebrae are distinct because they articulate (connect) with the rib cage, providing structural support and protection for vital organs in the thoracic cavity such as the heart and lungs. This anatomical arrangement is crucial for maintaining stability and facilitating respiratory movements. Therefore, recognizing that there are 12 thoracic vertebrae is essential for understanding human anatomy and body mechanics, particularly in fitness and rehabilitation contexts.
