Document Summary
Monday 22nd of october 2018: joints of the back. Posterior longitudinal ligament: accessory ligaments of the. Articular surfaces: inferior and superior surfaces of the adjacent vertebrae which is connected by fibrocartilaginous disc. The fibres of the adjacent lamellae at an angle of more than 60 degrees allow limited rotation while provide strong bond between the vertebrae. Receives sensory innervation only in the outer third: function, shock absorbers. Strong attachments between the bodies: information on discs: No iv discs between c1 and c2. As the spine travels inferiorly, the discs become larger and wider. Therefore, for every 5cm of the vertebral body means that there is 2cm of intervertebral disc: nucleus pulposus: Responsible of much of the flexibility and resilience in the vertebral column. Located between the uncinate processes of the bodies of c3/c4 or c6/c7. Articular surfaces = superior and inferior articular processes. Bear some weight in cervical and lumbar regions: ligaments of the vertebra:
