On either side the spinal nerve-roots, as they pierce the dura mater, carry with them into the intervertebral foramina tubular sheaths of the membrane, whilst in front loose fibrous prolongations— more numerous above and below than in the dorsal region— connect the tube of dura mater to the posterior common ligament of the vertebral column.

Dissection.—The tube of dura mater may now be opened with the scissors. The incision should be carried through the membrane in the mesial plane.
