Vertebral Anatomy and Functions

The video tutorial provides an in-depth look at the anatomy of the thoracic spine, covering the 12 thoracic vertebrae and their unique ability to attach ribs. It explains the types of ribs, including true, false, and floating ribs, and discusses the intervertebral discs and nerve roots. The structure of the vertebrae, including the vertebral body, pedicles, lamina, and spinous process, is detailed. The tutorial also covers the junctions where ribs connect to the vertebrae, such as the Costo transverse and Costo vertebral junctions.
