Denticulate ligaments
From Wikipedia, the free encyclopedia
Denticulate ligaments (also known as dentate ligaments) are lateral projections of the spinal pia mater[1] forming triangular-shaped ligaments that anchor the spinal cord along its length to the dura mater on each side.[2] There are usually 21 denticulate ligaments on each side, with the uppermost pair occurring just below the foramen magnum, and the lowest pair occurring between spinal nerve roots of T12 and L1.[1] The denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column.[citation needed]
