Dean Vaughn Medical Terminology Practice Test

Pariet- indicates wall. In anatomy, this root shows up in terms that describe the walls or boundaries of cavities or organs, not the surface or a separate layer. For example, the parietal bone forms part of the wall of the skull, and the parietal peritoneum lines the abdominal cavity. Because the idea here is a boundary that forms the wall, this root best matches the concept of “wall.”
