Select and explain. 
A. Anterior Longitudinal Ligament, B. Alar Ligament, C. Posterior Longitudinal Ligament, D. Cruciform Ligament
C: Posterior Longitudinal Ligament
Answer: C: Posterior Longitudinal Ligament 
Explanation: The Posterior Longitudinal Ligament interconnects the veebral bodies and interveebral disks posteriorly and runs anterior to the spinal cord within the veebral canal. The Ligamentum Nuchae is formed by supraspinous ligaments that extend from the seventh cervical veebra to the external occipital protuberance and crest. The Anterior Longitudinal Ligament runs anterior to the veebral bodies. The Alar and Cruciform Ligaments also lie anterior to the spinal cord. fig:- veebral column and ligaments
