Quizplus · Accepted Answer

The spinal cord terminates at the level of L1 to L2 vertebrae, and from there, nerve roots continue to descend through the vertebral column as the cauda equina. The cauda equina reaches the end of the vertebral column at the sacrum, and the spinal cord terminates in an opening called the sacral hiatus. Therefore, the best choice is E: sacral hiatus.
