How many thoracic vertebrae are there in the human body?

The human body has 12 thoracic vertebrae, which are labeled T1 through T12. Each thoracic vertebra corresponds to a pair of ribs, making them crucial in forming the ribcage that protects vital organs such as the heart and lungs. These vertebrae are unique in their structure and function, as they articulate with the ribs, allowing for both stability and a degree of flexibility in the upper body. The thoracic spine is situated between the cervical spine (in the neck region) and the lumbar spine (in the lower back). Understanding the number and location of these vertebrae is essential for fields such as anatomy, medicine, and mortuary science, as they have implications for surgical procedures, injury management, and the study of human remains.
