Craniosacral motion

Question 1

What are parts of primary respiratory mechanism PRM

Answer 1

CNS + CSF + dural membranes + cranial bones + sacrum

Question 2

the 5 elements of PRM

Answer 2

1 inherent motility brain and spinal cord
2 fluctuation CSF
3 movement intracranial and intraspinal membranes
4 articular mobility of the cranial bones
5 involuntary mobility of sacrum between ilia

Question 3

spinal cord changes during respiration

Answer 3

lengthens and things in exhalation

shortens and thickens on inhalation

Question 4

Cranial Rhythmic Impulse

Answer 4

10-14 cycles per minute

Question 5

factors that decrease rate of CRI

Answer 5

stress
depression
chronic fatigue
chronic infections

Question 6

factors that increase rate of CRI

Answer 6

vigorous physical exercise
systemic fever
following OMT to craniosacral mech

Question 7

where does dura mater attach

Answer 7

foramen magnum, C2 C3

S2 (respiratory axis)

Question 8

Sphenobasilar synchondrosis

Answer 8

articulation of sphenoid with occiput

Question 9

flexion SBS

Answer 9

midline bones of cranium and dura move cephalad (flexion)
paired bones cranium externally rotate
causes sacrum to counternutate (extend)

Question 10

change in head shape in flexion

Answer 10

widen head and decrease AP length

Question 11

extension SBS

Answer 11

midline bones move caudal and sacrum flexes

paired bones internally rotate

Question 12

what are the midline cranial bones

Answer 12

sphenoid, occiput ethmoid vomer

Question 13

strains at SBS

Answer 13

flexion/ext
torsion
sidebending and rotation
vertical strain
lateral strain
compression

Question 14

R torsion SBS

Answer 14

R sphenoid wing is most superior
anterior cranium rotate in one direction
posterior cranium rotate in other
AP axis

Question 15

in a sidebending rotation strain of SBS what are the axis

Answer 15

AP axis: anterior and post cranium rotate same direction

2 vertical axis,: foramen magnum and center sphenoid

Question 16

physiologic SBS motions

Answer 16

torsions and sidebending/rotations

Question 17

SBS extension

Answer 17

SBS deviates caudad

decreasing amount of flexion

Question 18

SBS flexion

Answer 18

SBS deviates cephalad

decreasing amount of extension

Question 19

axis in vertical strains

Answer 19

2 transverse axis

Question 20

superior vertical strain

Answer 20

sphenoid deviates superiorly

Question 21

L lateral strain

Answer 21

sphenoid deviates to the L

Question 22

axis in lateral strain

Answer 22

2 vertical

1 sphenoid and 1 foramen magnum

Question 23

palpation of cranium feels like parallelogram

Answer 23

lateral strain

Question 24

compression

Answer 24

decreased movement and can get rid of CRI

from trauma usually to back of head

Question 25

vagal SD can be from what cervical origin

Answer 25

OA AA and C2

Question 26

tinnitus, vertigo or hearing loss

Answer 26

CN VIII

Question 27

poor suckling in newborn, most likely SD

Answer 27

compression XII from occipital condyles | also dysfunctions IX X in jugular foramen

Question 28

Purpose venous sinus technique

Answer 28

increase venous flow through sinuses

Question 29

venous sinue technique

Answer 29

spread apart sutures on cranium on occiputal, transverse and sagittal sinuses

Question 30

CV4

Answer 30

enhance amplitude CRI | resist flexion phase and encourage extension then allow restoration

Question 31

bulb decompression

Answer 31

another name for CV4

Question 32

what enhances amplitude of CRI

Answer 32

CV4 technique

Question 33

vault hold purpose and hand position

Answer 33

``` asses SBS strains index finger on great wings sphenoid middle finger on temporal bone ring finger on mastoid little finger on squamous part of occiput ```

Question 34

V spread

Answer 34

separate restricted or impacted sutures

Question 35

lift technique

Answer 35

frontal and parietal lifts to balance membranous tension

Question 36

Indications craniosacral Tx

Answer 36

after birth trauma to PRM dentistry

Question 37

Absolute CI to craniosacral Tx

Answer 37

acute intracranial bleed or increased intracranial P

Question 38

relative CI to craniosacral Tx

Answer 38

known seizure or history of dystonia | traumatic brain injury
