This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Back region, Subject name: Anatomy
All of the following characteristics differentiate a typical cervical veebra from a thoracic veebra EXCEPT: 
Select and explain. 
A. Has a triangular veebral canal, B. Has foramen transversarium, C. Superior aicular facet is directed backwards & upwards, D. Has a small veebral body
C: Superior aicular facet is directed backwards & upwards
Answer: C: Superior aicular facet is directed backwards & upwards 
Explanation: Superior aicular facets are directed backwards & upwards in both cervical and thoracic regions, henceis not a differentiating feature. Veebral body is the smallest in the cervical region. Large veebral body is present at the level of lumbar veebra. Veebral foramen is triangular and large in the cervical veebra. The foramen is small and circular in thoracic veebra. Cervical veebrae are identified by the foramen transversarium in their transverse process.
