These are common radiograph views of the lumbar spine. Note again that the bony prominences of the spine are "flattened" in the AP projection. The junction between the thoracic spine and lumbar spine is seen by identifying the 12th ribs.

Identify the following:

1. T12 ribs

2. L1 vertebral body

3. L2 transverse process

4. L3 spinous process

5. L3 pedicle

6. L2 inferior articular facet

7. L3 superior articular facet

8. L3-4 intervertebral disc

9. L3-4 intervertebral foramen
