• B. 1, 7, 5, 12, 1
• C. 7, 12, 5, 1, 1
• D. 5, 12, 7, 1, 1
• E. 7, 5, 1, 12, 1

Answer 1

Answer: (C)

• 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
• Hence Number of vertebrae present on cervical, thoracic, lumbar, sacral and coccyx regions are respectively 7,12,5,1,1.
• So,the correct answer is '7, 12, 5, 1, 1'.
