How many synovial joints are identified for each cervical vertebra?
C1 = five, C2 = eight, C3-6 = eight, C7 = six
How many joints are identified at the vertebral body of each cervical vertebra?
C1 = none, C2 = ten, C3-6 = ten, C7 = eight
What features will allow discrimination between T2-T4 and T5-T8 segmental groups?
the vertebral body, transverse process, articular process and spinous process

the aortic impression
What is the height pattern of they typical thoracic vertebral body?
the posterior height is greater than the anterior height by one to two millimeters
What is the height pattern of intervertebral discs in the typical thoracic region?
the intervertebral discs are rather planar or flat with no apparent height difference between anterior and posterior heights
What is the principal cause of the posterior curve of the thoracic spine?
the vertebral body height differences
In terms of the anterior-posterior curves of the vertebral column, what direction will the thoracic spine face?
