Question

Where is the pars articularis found?

a. Superior and inferior aspect of the pedicle
b. Between the superior and inferior articular processes
c. Between the lamina and body spinous processes
d. Between the intervertebral disk and vertebra

Answer 1

The pars articularis is located between the superior and inferior articular processes of the vertebrae, which serve as important connection points between each vertebra in the spinal column.

Step-by-step explanation:

The pars articularis is found between the superior and inferior articular processes of a vertebra. Specifically, it is part of the vertebral arch and plays a crucial role in the articulation between vertebrae. The vertebral arch consists of pedicles and laminae, and the articular processes (both superior and inferior) arise from the vertebral arch. The superior articular process extends upward from the vertebral arch and articulates with the corresponding inferior articular process of the next higher vertebra, while the inferior articular process extends downward to articulate with the superior articular process of the next lower vertebra.
