Posterior height is greater than the anterior height by a few millimeters
What would be the direction of the vertical curve based on osseous features?
Posterior or kyphotic
What accounts for the direction o the typical cervical curve?
The intervertebral disc height
What is the direction of the typical cervical curve?
Anterior or lordotic
At which vertebral couple will the cervical curve again increase intervertebral disc height?
C5/C6
What is the sect o aging on the cervical vertebral body?
It diminishes the overall height o the vertebral body
What are the modifications o the superior epiphyseal rim of a typical cervical?
Anterior groove, posterior groove, right and left uncinate processes
What are the names o the lateral modification the superior epiphyseal rim?
Uncinate process, unciform process, uncovertebral process, uncus or lateral lip
What are the modifications o the inferior epiphyseal rim of a typical cervical?
Anterior lip, posterior lip, right and left lateral grooves
What is the joint classification for the anterior lip-anterior groove articulation?
Fibrous (amphiarthrosis) syndesmosis
What is the joint classification for the uncinate process-lateral groove articulation?
Modified synovial saddle (diarthrosis sellar)
What is the joint classification for the spongy bone-intervertebral disc articulation?

10
How many synovial joint surfaces are present on the vertebral body of a typical cervical?
4
What other terms are used to ID the uncinate process?
Unciform process, uncovertebral process, uncus, lateral lip
What is the name given to the uncinate process-lateral groove articulation?
Joint of Luschka or uncovertebral joint
The joint of Luschka is formed form what surfaces?
The uncinate processes and lateral groove
What is they functional significance o the joint of Luschka?
It appears to stabilize the intervertebral disc while accommodating flexion - extension and requiring pulped motion (axial rotation with lateral bending) in the cervical spine

Posteromedially
