Spinal Cord Anatomy

Denticulate Ligaments
Dura mater (blue) is incised and reflected bilaterally. Arachnoid (pink) is removed except at the top. Pia mater (not shown) covers the spinal cord and spinal roots (green).
Denticulate ligaments (purple) are bilateral thickenings of the collagen component of pia mater. Periodically each denticulate ligament has a lateral extension that attaches to dura mater and thus provides a means of suspending the spinal cord in subarachnoid fluid within the subarachnoid space. [Denticulate = L. small teeth].
