The pia mater has 21 pairs of denticulate ligaments which attach it to the arachnoid and dura maters. Named for their tooth like appearance, the denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column.
 A portion of the spinal cord, showing its right lateral surface. The dura is opened and arranged to show the nerve roots. |
