Nucleus pulposus
|
contains 70-90% of
water, depending on age and time of day (like water balloon) • Annulus Fibrosus contains 60-70% water. Its criss-cross (or zigzag) orientation helps to support the nucleus pulposus and resist compression or tensile force |
|
|
Disc Under Compression
|
Flexion of the
spine will cause the compression and bulging of the anterior annulus fibrosus and stretching of the posterior annulus fibrosus. The Nucleus pulposus will be pushed backward |
|
|
Anterior Longitudinal
Ligament (ALL) |
lies
anterior to the vertebral body |
|
|
Posterior Longitudinal
Ligament (PLL) |
lies posterior
to the vertebral body |
|
|
Facet joint
|
usually
biplanar or triplanar;Transverse orientation will help rotation;Sagittal orientation help flexion/extension; Frontal orientation helps side bending |
