[1] The denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column.

[citation needed] Their tooth-like appearance originates the word which derives from Latin denticulatus, from denticulus (meaning ‘small tooth’).

[1] Each denticulate ligament is composed of a single narrow fibrous strip that extends from the craniovertebral junction to T12.

Each ligament features 18-20 triangular extensions that attach to the dura at their apices[citation needed] in between successive nerve roots.

[citation needed] Denticulate ligaments are characterised by high extensibility (on average 50% of their initial length) and relatively low force necessary to rupture them (around 1 N).
