vertebral prac 1 - mvmts

Question 1

the intervertebral motion segment

Answer 1

two adjacent vertebrae and the connecting tissues that bind them together.

Question 2

Height of the superior articular process:

Answer 2

can resist fwd. sliding and/or rotation

Question 3

Zygapophysial joint orientation:

Answer 3

• sup. articular facets aligned in coronal plane resist ant. translation of the sup. vertebrae and even more vertical they are
• sup. articular facets aligned in sagital plane resist axial rotation of superior vertebrae

Question 4

ligaments

Answer 4

limit mvmt.

sensory feedback

Question 5

LIMITATIONS TO MOVEMENTS OF THE VERTEBRAL COLUMN:

flx

Answer 5

• Tall superior articular processes blocking anterior translation of the superior vertebra e.g. thoracic
• Zygapophysial joints aligned in the coronal plane e.g thoracic
• Compression in the anterior intervertebral disc
  Tension in the posterior annulus fibrosis fibres of the iv disc
• Tension in the PLL, ligamentum flavum, supraspinous lig / ligamentum nuchae
• Tension in the zygapophysial joint capsules
• Tension in posterior muscles / fascia
• Ribs

Question 6

LIMITATIONS TO MOVEMENTS OF THE VERTEBRAL COLUMN:

ext

Answer 6

• compression in post. IVD
• tension in ant. AF fibres of IVD
• tension in ALL
• tension in ZPJ capsule
• tension in ant. muscles/fascia

Question 7

LIMITATIONS TO MOVEMENTS OF THE VERTEBRAL COLUMN:

lat. flx

Answer 7

• tension in M-L. AF fibres of IVD
• tension in intervertebral ligaments
• tension in ZPJ capsule
• tension in M-L. muscles/fascia - obliques

Question 8

LIMITATIONS TO MOVEMENTS OF THE VERTEBRAL COLUMN:

rotation

Answer 8

Tension in aligned AF fibres

• ZPJ aligned in sagital plane
• oblique
• intertransverse
