Answer 1

between superior and inferior articular surfaces of vertebral bodies of adjacent vertebrae

Question 2

where is the posterior intervertebral joint located

Answer 2

between superior and inferior facets of adjacent vertebrae

Question 3

histological classification of anterior intervertebral joint

Answer 3

secondary cartilagenous

Question 4

histological classification of posterior intervertebral joint

Answer 4

synovial joint - gliding/plane joints

Question 5

2 layers of anterior IVD

Answer 5

nucleus pulposis and annulus fibrosis - in IVJ

Question 6

orientation of facets in PIVJ and movements - cervical

Answer 6

slope down anterior to posterior (oblique) - rotation, flexion, extension
