Answer 1

A secondary cartilaginous Symphysis joint

Question 2

State the articular surfaces: briefly describe the construction/structure of the joint

Answer 2

Vertebral Bodies Vertebral end plates covered in hyaline cartilage, Intervertebral discs. The superior surface of a vertebral body is covered in a cartilaginous endplate, this is attached to the annulus fibrosis of the intervertebral disc which then bonds to the cartilaginous endplate which is attached to the vertebral body above

Question 3

Name the ligaments that reinforce/support these joints

Answer 3

Anterior Longitudinal Ligament

-Posterior Longitudinal Ligament

Question 4

Give the attachments of one of these ligaments

Answer 4

ALL=Superior attachment to the anterior tubercle of the atlas, anterior aspect of vertebral bodies and intervertebral discs and attaches to the upper sacrum
PLL= Attaches to the body of S1 to the body of C2 plus attaches intervertebral discs and adjacent margins of the vertebral bodies in the vertebral canal.

Question 5

State the movement that this chosen ligament limits

Answer 5

Anterior Longitudinal Ligament=limits extension of the trunk

Posterior Longitudinal Ligament=limits flexion of the trunk

Question 6

Name a muscle which produces THAT movement
