Document Summary

Anterior longitudinal ligament : c1 superiorly to sacrum inferiorly, connects to anterior vertebral bodies + anterior side of intervertebral discs, altanto-occipital membrane continues it superiorly, anterior sacrococcygeal ligament continues inferiorly. Limits extension/hyperextension of the spine only ligament 2 do so. Posterior longitudinal ligament : c2 to sacral canal, strong connection to the annulus fibrosus of iv discs, gap where the vertebral body is basivertebral vein drains the medullary canal of the vb. Here: continued superiorly by tectorial membrane, continued inferiorly by posterior sacrococcygeal ligament. Ligamentum flavum : between lamina to lamina, c1 superiorly to sacral canal, elastin needed for spinal extension, so interlaminar distance decreases in size without buckling. Large portion of elastin fibres yellow appearance into the vertebral foramen and compressing the cauda aquina or spinal cord: restricts flexion. Supraspinous ligament : from l5 inferiorly upwards to become the nuchal ligament @ c7, tip of on spinous process to the next, resists flexion.
