Answer 8

Shortens

Question 9

In craniosacral extension the SBS moves in which direction?

Answer 9

Caudad

Question 10

In craniosacral extension the sacrum moves which direction?

Answer 10

Anterior (aka nutation)

Question 11

In craniosacral extension what is the associated phase of respiration?

Answer 11

Exhalation

*Extension = Exhalation

Question 12

Question 14

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

Answer 14

1) Vertical strains
2) Lateral strains
3) SBS Compressions

Question 15

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

Answer 15

• Coupling: sphenoid and occiput rotate opposite
• Named: HIGHER wing of sphenoid
• Axis: AP-axis

*Pic shows left cranial torsion

Question 16

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

Answer 16

• Coupling: sphenoid and occiput rotate SAME and sidebend OPPOSITE
• Naming: the convexity in sidebending
• Axis: (2) vertical axes and (1) AP-axis

*Pic shows left sidebending/rotation SD

Question 17

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

Answer 17

• 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

Question 18

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

Answer 18

• 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

Question 19

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

Answer 19

Lateral strain

Question 20

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

Answer 20

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

Question 21

What is the CV4 used for?

Answer 21

Increase CRI

Question 22

What are the 4 attachments for the Dura?

Answer 22

1) C2
2) C3
3) Foramen Magnum
4) Sacrum
