Explanation:

The dura mater is the outermost layer of the meninges. It extends inferiorly as the coccygeal ligament (filum terminale externum). The conus medullaris is the tapered end of the spinal cord. The denticulate ligament is a triangular-shaped ligament that anchors the spinal cord to the dura mater. The cauda equina is a bundle of spinal nerves. The subarachnoid space is between the arachnoid mater and pia mater, filled with cerebrospinal fluid.

Answer:

coccygeal ligament.
