Question

Number of lumbar vertebrae in the human skeleton is ________.

• A. 12
• B. 7
• C. 5
• D. 2

Answer 1

The correct option is C 5

• In humans, the vertebral column is formed by 26 serially arranged units called vertebrae and is dorsally placed.
  
• Each vertebra has a central hollow portion (neural canal) through which the spinal cord passes.
  
• The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions starting from the skull
  
• Lumbar vertebrae are found between the rib cage and the pelvis. Hence the number of lumbar vertebrae in the human skeleton is 5.
• So, the correct answer is '5'.
