Denticulate ligaments
The medulla spinalis and its membranes. (Ligamentum denticulatum labeled vertically at bottom left.)
Latin	ligamentum denticulatum
Gray's	subject #185 750
System
MeSH	[1]
Diagrammatic transverse section of the medulla spinalis and its membranes. (Denticulate ligament not labeled, but region is visible.)

The pia mater has 26 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.
