1

maximum number of common ligaments indentified with a vertebral couple

8

2

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

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

3

common ligaments that will attach to the vertebral body

anterior longitudinal ligament, intervertebral disc and posterior longitudinal ligament

4

common ligament that will attach to the vertebral arch

ligamentum flavum

between C2 and S1 inclusive

7

% of intervertebral disc height contribution to the length of each region of the vertebral column

cervical 22-25%
thoracic 20%
lumbar 33%

8

intervertebral disc histological composition

cells, collagen fibers, hydrated proteoglycan gel

9

names of the central, peripheral, and horizontal zones of the intervertebral disc

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

10

name of the growth zone of the intervertebral disc

transitional zone

11

maintains the heigh of the cervical intervertebral disc

uncinate process

12

effect of aging on the intervertebral disc nucleus pulposus

becomes more fibrous as water and proteoglycan concentrations diminish
