Answer 4

• Vigorous physical exercise
• systemic fever
• following OMT to the craniosacral mechanism

Question 5

The dura mater is the outermost membrane It is thick, inelastic and forms the falx cerebri and tentorium cerebella. What does it attach

Answer 5

• Foramen magnum
• C2
• C3
• S2 (posterior superior aspect)

Question 6

external rotation

-Wider and decrease in anterioposterior diamter

Question 8

counternutation

Answer 10

Squamous portion of temporal bone

Question 11

Answer 11

mastoid process of temporal bone

Question 12

Where is pinky finger in vault hold

Answer 12

squamous portion of occiput

Question 13

where is thumbs in vault hold

Answer 13

-hovering over sagittal sutures; NOT touching

Question 14

What are the physiologic strain patterns

Answer 14

• Flexion and extension
• Torsion
• Sidebending and rotation

Question 15

What are the nonphysiological strain patterns

Answer 15

• Vertical
• Lateral
• Compression

Question 16

A cranial torsion is named how

Answer 16

for the greater wing of the sphenoid that is more superior

Question 17

Describe the axis of rotation in torsion

Answer 17

-one AP axis and sphenoid and occiput rotating in opposite directions

Question 18

Describe the axis in Side bending rotation

Answer 18

• 2 distinct motions that occur simultaneously about three separate axes
• Rotationg occurs about an AP axis through the SBS (same axis as a torsion strain) but in the same direction
• The sidebending occurs about 2 parallel vertical axes (one through foramen magnum and the other through the center of the sphenoid)

Question 19

How is a sidebending rotation strain pattern names

Answer 19

names for side of convexity made by the sidebending

Question 20

Compression strain of the SBS can result in severely decreased CRI. It is usually due to what?

Answer 20

Trauma, especially to the back of the head

Question 21

(Occipital) condylar compression (CN XII) can result in what

Answer 21

poor suckling in the newborn . . Dysfunctions of CN IX and X at the jugular foramen can also cause suckling dysfunctions in the newborn

Question 22

What are the goals of Craniosacral treatment

Answer 22

• reduce venous congestion
• Mobilize articular restrictions
• Balance the SBS
• Enhance the rate and amplitude of the CRI

Question 23

What are the indications to craniosacral treatment

Answer 23

• After the birth of a child
• Trauma to the PRM
• Dentistry

Question 24

What are some complications that can occur with craniosacral treatment

Answer 24

• Headaches
• tinnitus
• dizziness
• alter heart rate, blood pressure, respirations, and GI irritability

Question 25

• skull fracture

Question 26

What are the relative contraindications to craniosacral treatment

Answer 26

• known seizure history or dystonia

- traumatic brain injury
