Which of the thoracic vertebrae have articular facets on each transverse process for rib articulation?

The correct answer highlights that the first 10 thoracic vertebrae feature articulating facets on each transverse process to accommodate rib attachments. This characteristic is significant because the thoracic spine's primary role involves providing stability and support while facilitating rib cage movement during respiration.

Each of the first 10 thoracic vertebrae possesses these transverse facets, allowing for the articulation of the corresponding ribs. The first rib articulates with the first thoracic vertebra, the second rib with the second thoracic vertebra, and so on up to the tenth rib. This anatomical arrangement is crucial for the connection between the vertebral column and the ribs, aiding in the expansion and contraction of the thoracic cavity during breathing processes.

While the 11th and 12th thoracic vertebrae do provide attachment for the ribs, they lack the transverse processes' articular facets, which is why the correct selection emphasizes only the first 10 thoracic vertebrae. Understanding this anatomical detail is vital for comprehending thoracic spine function and pathology in the context of physical therapy and rehabilitation.
