Vertebral Column (Backbone) -

  • Our vertebral column is formed by 26 serially arranged units called vertebrae and is dorsally placed. 
  • It is actually made up of 33 vertebrae. 
  • However, it consists of 26 bones because five sacral vertebrae are fused to form one sacrum and four coccygeal vertebrae are fused to form one coccyx.
  • It extends from the base of the skull and constitutes the main framework of the trunk.
  • 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; 5 fused) 
    • coccygeal (1; 4 fused)

 Sacrum:

  • The five sacral vertebrae are fused in the adult, forming one structure called the sacrum, which lies between the innominate bones of the pelvic girdle. 
  • The female sacrum is shorter, wider than the male sacrum.

 

Hence, the correct option is five
