The ligament extends inferolaterally from its medial attachment, [1] radiating laterally. [2] It represents the thickened inferior border of anterior and middle layers of thoracolumbar fascia . Inferiorly, the ligament is partially continuous with the lumbosacral ligament [ 1 ] (which may be considered an inferior subdivision of the iliolumbar ...
The posterior layer is attached to the spinous processes of lumbar and sacral vertebrae, and to the supraspinous ligament. [ 2 ] : 814–815 At sacral levels, the posterior layer attaches to the posterior superior iliac spines, and posterior iliac crest, fuses with the underlying erector spinae muscle aponeurosis, [ 2 ] : 814–815 and extends ...

The lumbosacral ligament extends obliquely inferior-ward from its medial attachment. Superiorly, it is partially continuous with the inferior margin of the iliolumbar ligament [ 2 ] (the lumbosarcal ligament can be considered an inferior subdivision of the iliolumbar ligament).
The quadratus lumborum muscle originates by aponeurotic fibers into the iliolumbar ligament and the internal lip of the iliac crest for about 5 centimetres (2.0 in). It inserts from the lower border of the last rib for about half its length and by four small tendons from the apices of the transverse processes of the upper four lumbar vertebrae.
The zonule of Zinn (/ ˈ t s ɪ n /) (Zinn's membrane, ciliary zonule) (after Johann Gottfried Zinn) is a ring of fibrous strands forming a zonule (little band) that connects the ciliary body with the crystalline lens of the eye. [1] The Zonular fibers a viscoelastic cables, although their component microfibrils are stiff structures.
