How many vertebrae are found in the thoracic region?

The thoracic region of the spine is comprised of 12 vertebrae, categorized from T1 to T12. These vertebrae are located in the upper and mid-back area and are characterized by their articulation with the ribs, which provides support and protection for the thoracic organs. The structure of these vertebrae allows for a limited range of motion compared to the cervical and lumbar regions, as they are designed to stabilize and support the rib cage during breathing and movement. Understanding the anatomy of the thoracic spine is essential for fitness instructors, as it plays a critical role in maintaining proper posture and movement patterns during exercise.
