[2025-10-02T00:19:19.865520] [PI reasoning] **Finding spinal cord termination**

I need to determine where the spinal cord terminates in adults, which typically ends at the lower border of L1 or the L1-L2 intervertebral disc. Many textbooks mention it ending at the lower border of L1, so I’ll go with answer A. I’ll make sure to find citations to back this up. Alright, I’m ready to search for more information!
