GENERAL HISTOLOGY

Detailed explanation-1: -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-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: -Anatomy. The bases of denticulate ligaments arise in the pia mater and are firmly attached to the arachnoid mater and dura mater at the apex.

Detailed explanation-4: -Spinal Meninges This dural sac is separated from the vertebrae by the epidural space. The spinal cord, in turn, is attached to the dural sac by the laterally placed denticulate ligaments and by the filum terminale internum.

Detailed explanation-5: -Pia mater-The innermost covering of the spinal cord, intimately adhering to its surface, stabilizes the spinal cord through lateral extensions of the pia called the denticulate ligaments, extending between the ventral and dorsal roots unto the dura mater.
