Which two regions of the back make up a roach back?

• A. Cervical and Thoracic
• B. Lumbar and Sacral
• C. Thoracic and Lumbar
• D. Thoracic and Sacral

Answer: (C)

A roached back is defined by an exaggerated convex curve in the mid to lower portion of the spine. The back is divided into regions, and the arch that creates the roached appearance comes from the thoracic (mid-back) and lumbar (lower back) sections. These two regions form the characteristic curved silhouette; the neck (cervical) region isn’t part of that arch, and the sacral region is lower and fused, not contributing to the roached curve. So, the combination of thoracic and lumbar is the region pair that produces a roached back.
