Ligamentous Support
Ligament Name
Description
Anterior Longitudinal Ligament (ALL)
A primary spine stabilizer
About one-inch wide, the ALL runs the
entire length of the spine from the base of
the skull to the sacrum. It connects the
front (anterior) of the vertebral body to the
front of the annulus fibrosis.
Posterior Longitudinal Ligament (PLL)
A primary spine stabilizer
About one-inch wide, the PLL runs the
entire length of the spine from the base of
the skull to sacrum. It connects the back
(posterior) of the vertebral body to the back
of the annulus fibrosis.
Supraspinous Ligament
This ligament attaches the tip of each
spinous process to the other.
Interspinous Ligament
This thin ligament attaches to another
ligament, called the ligamentum flavum
that runs deep into the spinal column.
Ligamentum Flavum
The strongest ligament
This yellow ligament is the strongest one. It
runs from the base of the skull to the
pelvis, in front of and behind the lamina,
and protects the spinal cord and nerves.
The ligamentum flavum also surrounds the
facet joint capsules.
