Vertebral column is part of the axial skeleton. It is the flexible column extending from neck to tail.

The human vertebral column consists of 33 vertebrae. These are divided into different regions, which correspond to the curves of the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx.

Cervical: The 7 cervical vertebrae are numbered C1 to C7 in neck. Its function is to support the weight of the head.

Thoracic: The 12 thoracic vertebrae are numbered T1 to T12. Main function of the thoracic spine is to hold the rib cage and protect the heart and lungs.

Lumbar: The 5 lumbar vertebrae are numbered L1 to L5. Main function of the lumbar spine is to bear the weight of the body.

Sacrum: There are 5 sacral vertebrae, which are fused together. Main function of the sacrum is to connect the spine to the hip bones.

Coccyx: The 4 fused bones of the coccyx provide attachment for ligaments and muscles of the pelvic floor.

Therefore the number of vertebrae present in cervical, thoracic, lumbar, sacral and coccyx regions respectively are 7, 12, 5, 5, 4.

So, the correct answer is '7,12,5,5,4.
