Which of the following structure helps in maintaining the centralized location of the spinal cord in the subarachnoid space?
Denticulate ligaments are lateral extensions of the pia mater which attaches to the arachnoid and dura mater. It helps in maintaining the centralized location of the spinal cord in the subarachnoid space. These ligaments are found between the ventral and dorsal roots, and project through the arachnoid mater in order to attach to the dura mater in a series of sawtooth projections. Filum terminale is an extension of the pia mater beyond the tip of the spinal cord which attaches to the coccyx in the veebral canal. Ref: Moon D.A., Foreman K.B., Albeine K.H. (2011). Chapter 1.
