What percentage of females typically have five lumbar vertebrae?

• A. 70%
• B. 80%
• C. 91%
• D. 95%

Answer: (C)

The correct percentage of females who typically have five lumbar vertebrae is 91%. Lumbar vertebrae are specific to the lower back region, and there is a common anatomical norm that most individuals possess five lumbar vertebrae. Studies in anatomical variation show that while there can be some deviations, the vast majority of the population, especially females, conform to the five-vertebrae standard. The relatively high percentage reflects the consistency in lumbar vertebrae count among females, underscoring the anatomical similarity across individuals. This information is critical for health professionals analyzing spinal health, diagnosing conditions related to lumbar vertebrae, or planning surgical interventions.
