The correct option is C 7, 12, 5, 1, 1
  • 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'.
