Question

Odontoid process occurs in

• A. Atlas
• B. Sacral
• C. Axis
• D. None of the above

Answer 1

The correct option is C Axis

• cervical vertebrae are the vertebrae present in the neck region of the body, immediately below the skull.
• The cervical vertebrae are numbered from C1 -C7. C1 is an atlas vertebra and C2(second cervical vertebra) is the axis.
  
• Axis vertebra has a superior tooth-like process called the odontoid process. The odontoid process articulates with the anterior arch of the atlas bone, where they form a pivot joint. The pivot joint allows the head to rotate.Hence odontoid process occurs in axis.
• So,the correct answer is 'Axis'.
