Q

Sally has a pain on the right side of her neck, if she tilts her head towards the right side she feels pain? What is causing this and why?

A

Most likely joint pain rather than muscle as she is closing the joints

  • The spinal cord through the foremen magnum
47
Q

What is the spinal cord protected by?

A

Meninges

48
Q

What do ligaments of the spine help do?

A

1) Reinforce the vertebral column
2) Stabilize intervertebral joints

49
Q

A

A hollow space inside the vertebrae which encloses the spinal cord

50
Q

  • transverse process & foramina
51
Q

Thoracic Spine Landmarks

A
  • spinous process
  • transverse process
  • transverse costal facet
  • superior costal facets
  • body
  • inferior notch
  • inferior costal facets
  • vertebral foramen
  • superior articular processes and facets
