1
Q

What is the maximum number of common ligaments identified in a vertebral couple?

A

eight

2
Q

What is the reason that nine common ligaments are identified but only eight will be attachedat any specific vertebral couple?

A

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

3
Q

Which common ligaments will attach to the vertebral body?

A

the anterior longitudinal ligament, intervertebral disc and posterior longitudinal ligament

4
Q

What common ligament/s will attach to the vertebral arch?

A

the ligamentum flavum

5
Q

Whast is the number of true intervertebral discs identified in the adult?

A

twenty three

6
Q

In the adult, which vertebral levels will demonstrate a true intervertebral disc?

A

those between C2 and S1 inclusive

7
Q

What is the intervertebral disc histologically composed of?

A

cells, collagen fibers, and a hydrated proteoglycan gel

8
Q

What is the cervical nucleus pulposus composed of?

A

fibrocartilage

9
Q

What is the water concentration in the lumbar nucleus pulposus at birth and after thirty?

A

birth…88%; thrity…70%

10
Q

What is the consequence of non-aggregated glycosaminoglycans in the lumbar nucleus pulposus?

A

the nucleus pulposus will loose water under deformation conditions

11
Q

What cell is associated with the nucleus pulposus until about age eleven?

A

notochord cells

12
Q

What cells are associated with the mature nucleus pulposus?

A

reticulocyte-fibroblast and chondroblast

13
Q

Which type of collagen is dominant in the nucleus pulposus?

A

collage type II

14
Q

What general tissue location is described as having an abundance of collage type II fibers?

A

cartilage

15
Q

What is the role of collagen fiber type II fibers based on locations where is it dominant?

A

it apperas to be related to tissues having a deformation - reformation ability
