How many joint surfaces present on upper surface of typical cervical vertebral body? Lower surface?
5; 5
How many joint surfaces present on a vertebral body of typical cervical? How many are synovial?
10; 4
Name given to uncinate process-lateral groove articulatio ?
Joint of Luschka or uncovertebral joint
What does recent literature suggest as nature of joint of Luschka?
Joint representative of IVD aging which results in loss of lamellar integrity near joint
Functional significance of joint of Luschka?
Appears to stabilize IVD while accomidating flexion-extension and requiring coupled motion (axial rotation w/ lat. Bend) in cervical spine
