Question: 1 / 415

How many vertebrae make up the thoracic spine?

5

12

The thoracic spine consists of 12 vertebrae, which are labeled T1 through T12. This section of the spine is located between the cervical spine (neck region) and the lumbar spine (lower back) and plays a crucial role in providing stability and support for the upper body. The 12 thoracic vertebrae are unique in that they articulate with the ribs, forming the posterior part of the rib cage. This arrangement not only protects vital organs such as the heart and lungs but also allows for a degree of flexibility and movement in the upper body. Understanding the number and function of the thoracic vertebrae is essential for anyone studying human anatomy, particularly in the context of personal training and physical fitness.
