An accurately positioned oblique projection of the first through fourth lumbar vertebrae will demonstrate the classic "Scotty dog." What bony structure does the Scotty dog's neck represent?

A. Superior articular process

B. Pedicle

C. Transverse process

D. Pars interarticularis

Answer: Option (D)

Explanation:

Here, in this scenario we can state that the bony structure of Scotty dog's neck tends to represent Pars interarticularis. The pars interarticularis also referred to as pars is a segment of the vertebra that is placed in between the secondary and the superior articular mechanism of that of facet joint. In a crosswise plane, the pars lies in between pedicle and the lamina.
