Question 1

maximum number of common ligaments indentified with a vertebral couple

Answer 1

8

Question 2

what is the reason that 9 common ligaments are identified but only 8 will be attache at any specific vertebral couple

Answer 2

ligamentum nuchae and suprapsinous ligaments attach to the spinous tubercles, but only one of these will be identified at a single vertebral couple

Answer 9

nucleus pulposus- central zone
annulus fibrosis- peripheral zone
cartilaginous end plate- horizontal zone

Question 10
