Conus medullaris

Dr Jeremy Jones et al.

The conus medullaris is the terminal end of the spinal cord. After the cords termination at the level of L1-2, the nerve roots descend within the spinal canal as individual rootlets, collectively termed the cauda equina.

Extending from the conus is a delicate strand of fibrous tissue called the filum terminale that acts to give longitudinal support to the cord.
