A

33

35
Q

How many different discs do we have

A

23

36
Q

A

7

37
Q

A

12

38

41
Q

What are zygoapophyseal joints?

A
  • the facet joints
  • two vertebrae
  • the intervertebral disc
42
Q

what are the four parts of the intervertebral discs?

A
  1. Anulus fibrosus
    - rings of fibrocartilage and collagen
    - they help with weight distribution and flexibility in the spine
    - form a barrier between the nucleus pulposus
  2. Nucleus pulposus
    - good elasticity
    - transmits loads to the bones
  3. End plates
    - superior and inferior end plate
    - made of fibrocartilage
    - contain nucleus pulposus
43
Q

What are the 7 bones and landmarks on the posterior side of the sacrum?

A
  • sacrum canal
  • sacral tuberosity
  • auricular surface
  • lateral sacral crest
  • posterior sacral foramen
  • superior articular facet
  • sacral hiatus
