What extra articulations do we have in the thoracic spine?

• Costovertebral and sacroilliac joints

• Atlantoaxial and sacroilliac joints

• Costovertebral and costotransverse joints

At roughly what angle do the lumbar facet joints articulate with each other?

• 0 degrees

• 45 degrees

• 60 degrees

• 90 degrees

For what reason is extension limited in the thoracic spine?

• The atlantoaxial joint gets in the way

• The inferiorly pointing spinous process get in the way

• There is only 2-5 degrees of movement at this joint

• The rib cage limits movement in the sagital plane
