Question

The vertebral column of a young man gets dislocated from the skull. Which of the following parts are most likely to be involved directly?

• A. One occipital condyle and atlas vertebra
• B. Hyoid bone and axis vertebra
• C. Two occipital condyles and axis vertebra
• D. Two occipital condyles and atlas vertebra

Answer 1

The correct option is D Two occipital condyles and atlas vertebra

The two occipital condyles help the skull articulate to the vertebral column. Hence humans are said to have a dicondylic skull. The first cervical vertebra is called the atlas which joins the skull to the vertebral column. On dislocation of the vertebral column from the skull, the atlas vertebrae would detach from the occipital condyles.
