Movement of the vertebral column

Question 1

Factors influencing movement of the vertebral column

Answer 1

IV discs
Shape of articular facets
Joint capsule
Surrounding tissues and structures

Question 2

What limits movement in the cervical region?

Answer 2

Upwards slope of SAF allows for free flexion and extension

Lateral flexion and rotation coupled and possible

Question 3

What limits movement in the thoracic region?

Answer 3

Lack of upwards inclination of SAF limits flexion
Extension inhibited by adjacent SP rotation
Rotation possible but limited by ribs
Lateral flexion limited by rib position and attachment to sternum

Question 4

What limits movement in the lumbar region?

Answer 4

Flexion greater than extension or lateral flexion

Rotation limited by tight bony contact between adjacent facets
