The prompt asks: 'Who am I? I am a structure of the spinal cord. I am a fibrous extension of the Pia Mater. I attach to the posterior coccyx.'

First, identify the structure described: it is a fibrous extension of the Pia Mater, which narrows into a filament that anchors the spinal cord. Among the pia-derived structures in the spinal region, the key anchoring filament is the filum terminale.

Now, assess what the filum terminale does and where it attaches: The filum terminale consists of two parts—the filum terminale internum (within the dural sac) and the filum terminale externum (exiting the sac). Its primary role is to anchor the inferior end of the spinal cord (conus medullaris) to the coccyx, effectively attaching to the posterior coccyx to provide longitudinal stability.

Consider potential misidentifications to avoid confusion: 
- Denticulate ligaments are also extensions of the pia mater, but they function as lateral suspensory ligaments that attach the spinal cord to the dura mater along its sides; they do not attach to the coccyx and are not described as a single extension to the coccyx.
- The cauda equina refers to the bundle of nerve roots below the conus medullaris, not a fibrous extension of pia mater.
- The filum terminale internum is within the dural sac and not the external attachment to the coccyx, and the externum specifically reaches the coccyx.

Putting this together, the structure that matches all three clues—structure of the spinal cord, fibrous extension of the Pia Mater, and attachment to the posterior coccyx—is the filum terminale.

Note: In this item, there is no list of answer choices provided to compare against, so the conclusion relies on matching the described characteristics to the known anatomy of the filum terminale and its role as the pia-derived anchoring filament to the coccyx.
