The joint between the tubercle of a rib and the transverse process of the corresponding thoracic vertebra is classified as which type of synovial joint?

• A Synovial ellipsoid joint
• B Synovial pivot joint
• C Synovial saddle joint
• D Synovial plane joint ✓

Explanation

The costotransverse joint (between the articular facet of the rib tubercle and the transverse process of the corresponding thoracic vertebra) is a synovial plane joint. It permits gliding movements that contribute to elevation and depression of the ribs during respiration. The first and lower three ribs may have slight variations, but the classic costotransverse joint is a synovial plane joint.
