cranial physio motion

Question 1

5 tenets of the primary respiratory mechanism

Answer 1

1. The inherent rhythmic motion of the brain & spinal cord
2. Fluctuation of the CSF
3. Mobility of intracranial & intraspinal membranes (RTM)
4. Articular mobility of cranial bones
5. Involuntary mobility of the sacrum between the ilia

Question 2

reciprocal tension membrane (RTM) consists of

Answer 2

1. falx cerebri
2. tentorium cerebelli
3. formed by dural reflections

(dura is contiguous with periosteum of the skull)

Question 3

cranial physiologic motion influences

Answer 3

1. dural membrane (RTM)
2. coiling/uncoiling of CNS
3. fluctuation of CSF

Question 4

cranial physiologic motion correlate with

Answer 4

1. flexion-external rotation-inhalation
2. extension-internal rotation-exhalation

(inhalation/exhalation related to respiratory phases of primary respiratory mechanism (PRM))

Question 5

sacral movement: motion occurs around

Answer 5

transverse axis in area of 2nd sacral segment posterior to the canal (respiratory axis)

Question 6

sacral movement includes

Answer 6

1. flexion (counternutation) - base moves posterosuperiorly and apex moves anteriorly toward pubes
2. extension (nutation) - base moves anteriorly and apex moves posteriorly

Question 7

how does cranial influence sacrum?

Answer 7

spinal dura/core link

Question 8

midline bones include

Answer 8

1. sphenoid
2. occiput
3. ethmoid (median plate)
4. vomer
5. sacrum

Question 9

midline bones physiologic motion occurs during which phase?

Answer 9

flexion and extension phases

Question 10

paired bones include

Answer 10

1. temporal
2. parietals
3. frontals
4. ethmoid (lateral mass)
5. nasals
6. lacrimals
7. maxillae
8. palatines
9. zygomae
10. inferior conchae
11. mandible

Question 11

paired boned physiologic motion occurs during which phase?

Answer 11

external and internal rotation phases

Question 12

cranial rhythmic impulse consists of 2 phases

Answer 12

1. flexion - external rotation of the paired bones with increased width of the head (transverse diameter)
2. extension - internal rotation of the paired bones with increased length of the head (AP diameter)

Question 13

internal rotation is paired with _____. external rotation is paired with ______

Answer 13

1. internal with extension and exhalation

2. external with flexion and inhalation

Question 14

position of vault hold

Answer 14

hands palpate the frontal, sphenoid, temporal, and occipital bones, and the membranes and fluids between them

Question 15

what does the vault hold allow the operator to do?

Answer 15

enables operator to feel the dysfunction in order to initiate treatment

Question 16

flexion and extension phase include what motion and around which axis?

Answer 16

rotational around 2 transverse axis - level of foramen magnum and body of sphenoid

Question 17

what motion occurs at SBS during flexion phase?

Answer 17

1. basiocciput and basisphenoid move cephalad

2. occipital squama and wings of sphenoid move cadually

Question 18

what motion occurs at SBS during extension phase?

Answer 18

1. basiocciput and basisphenoid move caudad

2. occipital squama and wings of sphenoid move cephalad
