Fig. 39-9. Oblique view of the lumbar vertebrae. Note the very small twelfth rib, the joints between the articular processes of the lumbar vertebrae (the arrow indicates the joint between L.V.1 and L.V.2), and the sacrum. In this view the outline of a Scotch terrier is formed by the transverse process (snout, overlapping the vertebral body), the superior articular process (ear), and the inferior articular process (forepaw). The neck of the dog corresponds to the important pars interarticularis, injury to which may result in spondylolisthesis. Click for high resolution image.
