Flashcards in VI. Regions of the Vertebral Column: Cervical Region: A) Typical Cervical Vertebrae C3-C6: 1) Vertebral Body. (Pg. 47) Deck (23):
What is the shape of the typical cervical vertebral body from the cranial view?
What is the effect of aging on the cervical vertebral body?
it diminishes the overall height of the vertebral body
What is the appearance of the typical cervical vertebral body from the lateral view?
posterior height is greater than anterior height by a few millimeters
What would be the direction of the cervical curve based on osseous features?
posterior or kyphotic
What accounts for the direction of the typical cervical curve?
the intervertebral disc height
What is the direction of the typical cervical curve?
anterior or lordotic
Which vertebral couples will demonstrate a decrease in intervertebral disc height?
C2/C3 down to C4/C5
At which vertebral couple will the cervical curve again increase intervertebral disc height?
What are the modifications of the superior epiphyseal rim of a typical cervical?
anterior groove, posterior groove, right nad left uncinate processes
What are the names of the lateral modification of the superior epiphyseal rim?
uncinate process, unciform process, uncoverteral process, uncus or lateral lip
What are the modifications of 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 longitudinal ligament-anterior groove articulation?
fibrous (amphiarthrosis) syndesmosis
What is the joint classification for the posterior lip-Posterior longitudinal ligament-posterior groove articulation?
fibrous (amphiarthrosis) symphysis
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?
cartilaginous (amphiarthrosis) symphysis
How many joints are present on the upper surface of a typical cervical verteral body?
How many joints are present on the lower surface of a typical cervical vertebral body?
How many total joint surfaces are present on the vertebral body of a typical cervical?
What is the name given to the uncinate process-lateral groove articulation?
joint of Luschka or uncovertebral joint
The joint of Luschka is formed from what surfaces?
the uncinate process and lateral groove
How many total synovial joint surfaces are present on the vertebral body of a typical cervical?
What is the functional significance of the joint of Luschka?
it appears to stabilize the intervertebral disc while accommodating flexion - extension and requiring coupled motion (axial rotation with lateral bending) in the cervical spine
