Lordosis is defined as an increase in which spinal curve?

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

Answer: (A)

Lordosis is the inward curvature of the spine when seen from the side. When this inward bend becomes more pronounced, it’s called hyperlordosis. The lumbar region is the classic site for this increased inward curve; the thoracic and sacral regions are normally kyphotic (outward-facing curves) and thus do not represent lordosis when the curvature increases. While the cervical spine also has a natural lordotic curve, in this context the question points to the lumbar region as the area where an increase defines lordosis.
