Question

Nucleus pulposus represents

• A. Remains of notochord
• B. Area of ossification
• C. Region of non-ossification
• D. Area resistant to frictional damage

Answer 1

Answer: (A)

Remains of notochord

• Nucleus pulposus forms the inner core of the vertebral disc of mammals.
  
• This region is made up of a jelly-like substance which consists of water and a loose network of collagen fibres.
• This elastic inner core helps the vertebral disc to withstand compression and torsion.
• So, the correct answer is 'Remains of notochord'.
