How many thoracic vertebrae are present in the human body?

The human body contains 12 thoracic vertebrae. These vertebrae are a critical component of the spine, located in the upper and mid-back region, and are numbered T1 to T12. Each thoracic vertebra articulates with a pair of ribs, contributing to the structure and stability of the thoracic cage, which protects vital organs such as the heart and lungs. The presence of 12 thoracic vertebrae is constant in humans, making it a standard anatomical feature. This number is important for understanding both human anatomy and the biomechanical properties of the spinal column.
