1

What are the 2 motions of the midline cranial bones?

1) Flexion

2) Extension

2

What are the midline cranial bones vs. paired cranial bones?

Midline (SOVE) = Sphenoid, Occiput, Vomer, Ethmoid

Paired = all the others

3

What are the 2 motions of the paired cranial bones?

1) IR

2) ER

4

In craniosacral flexion the SBS moves ________.

Cephalad

5

In craniosacral flexion the sacrum moves?

Posterior (aka counternutation)

6

In craniosacral flexion what is the associated phase of respiration?

Inhalation

7

In craniosacral flexion which direction do the paired bones move?

ER

8

What occurs to the AP diameter in craniosacral flexion?

Shortens

9

In craniosacral extension the SBS moves in which direction?

Caudad

10

In craniosacral extension the sacrum moves which direction?

Anterior (aka nutation)

11

In craniosacral extension what is the associated phase of respiration?

Exhalation

*Extension = Exhalation

12

In craniosacral extension which direction do the paired bones move?

IR

13

What occurs to the AP diameter in craniosacral extension?

Lengthens

14

What are the 3 non-physiologic SD's associated w/ the cranium?

1) Vertical strains

2) Lateral strains

3) SBS Compressions

15

For cranial torsions what is the coupling (sphenoid/occiput), naming, and axis?

Coupling: sphenoid and occiput rotate opposite

Named: HIGHER wing of sphenoid

Axis: AP-axis

*Pic shows left cranial torsion

16

For cranial sidebending/rotation SD's what is the coupling (sphenoid/occiput), naming, and axis?

Coupling: sphenoid and occiput rotate SAME and sidebend OPPOSITE

Naming: the convexity in sidebending

Axis: (2vertical axes and (1AP-axis

*Pic shows left sidebending/rotation SD

17

For cranial vertical strains what is the coupling (sphenoid/occiput), naming, and axis?

Coupling: sphenoid and occiput rotate same direction about 2 transverse axes (i.e., flexion at the sphenoid coupled with extension at the occiput)

Named: SBS translation

Axis: (2) Transverse Axis

18

For cranial lateral strain what is the coupling (sphenoid/occiput), naming, and axis?

Coupling: sphenoid and occiput spin in same direction about each vertical axis

Named: SBS translation (also can name for which wing is higher = highest corner of the parallelogram)

Axis: (2) Vertical Axes

19

A parallelogram head is associated with what type of cranial SD?

Lateral strain

20

Which 4 fingers are used in the vault hold and where is each finger placed?

1) Index finger --> greater wings of the sphenoid

2) Middle finger --> temporal bone (in front of ear)

3) Ring finger --> mastoid process of temporal bone

4) Pinky finger --> squamous portion of occiput

21

What is the CV4 used for?

Increase CRI

22

What are the 4 attachments for the Dura?

1) C2

2) C3

3) Foramen Magnum

4) Sacrum
