Spine Ligaments Flashcards
Anterior longitudinal ligament function
Limits extension
Reinforces anterolateral portion of annulus fibrosis and anterior aspect of IV joints
Anterior longitudinal ligament region
C2 to sacrum. Well developed in cervical, lower thoracic, and lumbar regions
Anterior atlantoaxial ligament function
Limits extension. Continuation of the anterior longitudinal ligament
Anterior atlantoaxial ligament region
C2 to occipital bone
Posterior longitudinal ligament function
Limits forward flexion
Reinforces posterior portion of anulus fibrosis
Posterior longitudinal ligament region
C2 to sacrum. Broad in cervical and thoracic region and narrow in lumbar region.
Tectorial membrane function
Limits forward flexion. Continuation of posterior longitudinal ligament.
Tectorial membrane region
C2 to occipital bone
Ligamentum flavum function
Limits forward flexion esp in lumbar area where it resists separation of laminate
Ligamentum flavum region
C2 to sacrum. Thin, broad, and long in cervical and thoracic region and thickest in lumbar region
Posterior atlantoaxial ligament function
Limits flexion. Continuation of the Ligamentum flavum
Posterior atlantoaxial ligament region
C1 to C12
Supraspinous ligaments function
Limits forward flexion
Supraspinous ligaments region
C7-L3/L4. Weak in lumbar region
Ligamentum nuchae function
Limits forward flexion
