All of the following statements are true regarding ligamentum denticulatum except
Ligamentum denticulatum is not a modification of arachnoid mater. It is a modification of the pia mater. The ligamentum denticulatum is a flat fibrous sheet on either side of the spinal cord present between the ventral and dorsal spinal roots. It serves as a neurosurgical landmark for hemisectioning of the spinal cord. (Option C) Its medial border is continuous with the subpial connective tissue and lateral border forms a series of 21 triangular processes on each side connecting it to the dura mater giving it a serrated appearance. (option B and Option D) The lowest of the dentate ligaments lies between the T12 and L1 spinal nerves. Ref: Gray&;s Anatomy 41st edition Pgno: 765
