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)

 Lumbar Vertebrae:

  • These are 5 in number present in the abdomen. 
  • They are the largest and strongest in the vertebral column. 
  • Their processes are short and thick. 
  • The spinous pro­cesses are thick and broad and project posteriorly.

Hence, the correct option is b. abdominal region
