Accepted Answer

The area between the dura mater (outermost layer of the meninges) and the vertebrae is known as the epidural space. The subarachnoid space is between the arachnoid mater and the pia mater, the filum terminale is a strand of fibrous tissue that attaches to the end of the spinal cord and anchors it to the coccyx, and the conus medullaris is the tapered end of the spinal cord before it becomes the cauda equina.
