the filum terminale which extends from the conus medullaris.
The inferior continuation of the pia mater to the coccyx is the filum terminale, a slender filament of connective tissue. It helps to anchor the spinal cord within the spinal canal and provides longitudinal support to the spinal cord.
Spinal cord
The spinal cord sends messages to the brain,if we didn't have a spinal cord we couldn't do anything
The spinal cord
Filum terminale or terminal thread is a fragile fibrous tissue strand which is the longitudinal support of the spinal cord. Its upper part is called filum terminale internum and the lower part called filum terminale externum.

Spinal nerves
The tissue in the spinal cord is composed of nervous tissue.
The denticulate ligaments, I know, prevent lateral movement of the spinal cord within the thecal sac (as stated in Sectional Anatomy for Imaging Professionals, 3rd Edition, page 211). I have yet to find if the denticulate ligaments are also responsible for longitudinal movements or not. I hope this helps.
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
The Vertebral Column (aka, the spine or backbone) protects the spinal cord and supports the head and back.
The longitudinal bundles of nerve fibers within the spinal cord that comprise major nerve pathways are called tracts. These tracts are organized based on their function and transmit information to and from different regions of the body to the brain.
