The Front Leg of the Scotty dog corresponds to which vertebral feature?

Explanation:
On the oblique view of a lumbar spine, the posterior elements line up to resemble a Scotty dog. The front leg of that dog corresponds to the inferior articular process, the downward-protruding part of the facet joint that forms the lower facet of the vertebra. This orientation helps you identify the facet joints on the oblique view, and remember that the pars interarticularis is the “neck” between the superior and inferior articular processes.
