What are delicate shelves of pia mater; attach the spinal cord to the vertebrae?
A
Conus medularis
B
Denticulate ligament
C
Filum Terminale
D
Epineurium
Explanation: 

Detailed explanation-1: -Denticulate ligaments (also known as dentate ligaments) are lateral projections of the spinal pia mater forming triangular-shaped ligaments that anchor the spinal cord along its length to the dura mater on each side.

Detailed explanation-2: -The denticulate ligaments are bilateral triangular lateral extensions of pia mater that anchor the spinal cord to the dura mater. They are formed by pia mater of the spinal cord coursing in-between the dorsal and ventral nerve roots bilaterally.

Detailed explanation-3: -The pia mater has paired specializations called denticulate ligaments, which extend laterally from the surface of the spinal cord and pierce the arachnoid to attach to the inner aspect of the dura mater at 21 pairs of denticulations (dentate means tooth-like-these are tooth-like lateral projections).

Detailed explanation-4: -Definition. English. Denticulate ligaments are the triangular-shaped extensions of the spinal pia mater, that extend sideways from the spinal cord. In total, 21 pairs of denticulate ligaments can be seen all along the length of the spinal cord (from the foramen magnum to T1 vertebral level).

Detailed explanation-5: -The spinal cord is anchored distally by the filum terminale, a fibrous extension of the pia mater anchoring the spinal cord to the coccyx.
