How do you identify the lumbar vertebrae?
Distinguishing features of the lumbar vertebrae include a thick and stout vertebral body, a blunt, quadrilateral spinous process for the attachment of strong lumbar muscles, and articular processes that are oriented differently than those found on the other vertebrae.
What features are unique to lumbar vertebrae?
