Which Scotty dog feature corresponds to the pars interarticularis?

Explanation:
On the oblique view of the lumbar spine, the Scotty dog is formed by various parts of the vertebra. The pars interarticularis is the narrow segment between the superior and inferior articular processes, which appears as the neck of the Scotty dog. Therefore, the feature that corresponds to the pars interarticularis is the neck. Recognizing this helps you assess for pars fractures (spondylolysis) in that specific region. The other features of the Scotty dog correspond to different parts of the vertebra, not the pars interarticularis.
