[2025-09-30T04:47:35.477252] [PI reasoning] **Analyzing epidural plexus location**

I need to clarify the location of the epidural venous plexus, which is the internal vertebral venous plexus situated in the epidural space between the dura mater and the bones of the vertebral canal. The options say "in vertebral canal below duramater" and "above duramater." If "below" implies inside the dura, that contradicts the definition because that would mean it's subdural. I want to ensure I choose the correct response based on this understanding.
