Q

Anterior Longitudional Ligament

A
  • strong, broad fibrous band that covers and connects the anterolateral aspects of the vertebral bodies and IV discs
  • limits extension

Q

Posterior Longitudional Root

A
  • narrower, somewhat weaker band that runs within the vertebral canal along the posterior aspect of the vertebral boidies
  • resists hyperflexion
  • prevents posterior herniation of nucleus puplosus

17
Q

Rotatores Muscle Actions

A
  • Bilateral: extends thoracic spine
  • Unilateral: rotates thoracic spien to opposite side
18
Q

Multifidus Muscle Actions

A
  • Bilateral: extends spine
  • Unilateral: flexes spine to same side, rotates to opposite side
19
Q

Semispinalis Muscle Actions

A
  • Bilateral: extends thoracic and cervical spines and head
  • Unilateral: bends head, cervical and thoracic spines to same side, rotates to opposite side
20
Q

Motion is always referenced to the movement of the __ surface of the vertebrae

A

Anterior/Superior

21
Q

Muscle Dysfunction Model of Somatic Dysfunction

A
  • Rotatores muscles affect a single segment – sidebend and rotate in the same direction, dysfunction would affect a single segment; type two dysfunction associated with this muscle
  • Semispinalis and Multifidus affect multiple segments – sidebend and rotate in opposite directions, dysfunction would affect multiple contiguous segments; type one dysfunction associated with these muscles
22
Q

Facet Model of Somatic Dysfunction

A
  • In the neutral range the facets are not engaged
  • In flexion the facets are open (if the facet is dysfunctionally open and won’t close then the vertebrae is flexed; stuck open = sidebend and rotate away)
  • In extension the facets are closed (if a facet is dysfunctionally closed and won’t open, the vertebra is extended; stuck closed = sidebend and rotate towards)
23
Q

Fryette Type One Somatic Dysfunction

A
  • in the neutral range (not flexed or extended), sidebending and rotation are coupled in opposite directions
  • rotation is towards the convexity of the spine
  • typically tends to be a group of vertebra
24
Q

Fryette Type Two Somatic Dysfunction

A
  • in sufficient flexion or extension (non-neutral), sidebending and rotation are coupled in the same direction
  • rotation is towards the concavity
  • tends to be a single vertebra
  • Muscle Dysfunction Model: rotatores muscles affect a single segment (sidebend and rotate in same direction)
25
Q

Nelson’s Third Principle of Somatic Dysfunction

A
  • initiating movement of a vertebral segment in any plane of motion will modify the movement of that segment in other planes of motion
  • if motion is restricted in one direction, motion will also be restricted in other directions
  • if motion is improved in one direction, motion will also improve in other directions
