Answer 1

The correct option is D It is absent in man

• Cervical vertebrae are the vertebrae present in the neck region of the body, immediately below the skull.
• The cervical vertebrae are numbered as C1-C7. The first two, C1 and C2, are highly specialized and are given unique names: atlas (first cervical vertebra) and axis (second cervical vertebra).
• The neural spine (the spinous process of the neural arch of a vertebra) is absent in the atlas vertebra of man. It consists of an anterior and a posterior arch and elongated transverse processes.
  
• So, the correct answer is 'It is absent in man'.
