Flashcards in Cranial II Deck (45):
1

What are the five components of the primary respiratory mechanism?

-Inherent motility of the CNS
-Fluctuation of the CSF
-Reciprocal tension membrane
-Mobility of the cranial bones
-Mobility of the sacrum between the ilia

2

What is the cranial rhythmic impulse? What causes it?

Palpable, rhythmic fluctuations brought about by the PRM

Glial cells firing--not breathing movements

3

Sacral movement is influenced by primary or secondary respiratory movement?

Secondary

4

True or false: if the patient were to hold their breath, you cannot pick up the tidal movement of the sacrum from the cranial respiratory mechanism

False-- you can?

5

What is "primary" respiration?

Inherent motility of the CNS

6

What is "secondary" respiration?

Sacral movement associated by the lungs

7

True or false: the CSF flow is always present, but may be influenced by underlying factors ("waves on top of it")

True?, but ALWAYS underlined by the tide

8

Can you consciously change the tidal mechanism?

No

9

How can you influence the CSF tide?

Utilize the secondary forces from the sacrum--the collaborative effort of the muscles of respiration will influence the motion

10

What bones flex and extend in the craniosacral mechanism?

Midline bones--sphenobasilar synchondrosis

11

Does physiologic motion of the SBS move in opposite directions, or the same?

Opposite

12

When the SBS flexes, does it rise or fall? Does the angle underneath it increase or decrease?

Rise
Decrease

13

When the SBS extends, does it rise or fall? Does the angle underneath it increase or decrease?

SBS falls
Angle increases

14

What are the two axes that the SBS moves about?

-Through the base of the sphenoid, above the foramen magnum of the occiput

15

When the SBS flexes, what happens to the index and little fingers move?

Move away and widen

16

What the SBS extends, what do the index and little fingers do?

Towards you, and come together

17

What happens to the occiput and the sphenoid with SBS extension?

Moves toward Dr

18

Flexion of the midline bone is paired with what motion of the paired bones?

External rotation

19

Extension of the midline bone is paired with what motion of the paired bones?

Internal rotation

20

As the head goes into (__), is also feels wider, and fuller in your hands

Flexion

21

Axis of rotation about the temporal bones is through what? What happens as these axes anteriorly?

Through the petrous ridge

Converge as they move anteriorly

22

What is the reciprocal tension membrane?

The dura mater

23

What is the normal rate of the CRI?

6-12 per minute

24

True or false: Respiration can actively influence the tide of the CSF

False--the collaborative effort from the muscles involved in respiration will influence it, not the respiration itself

25

What are the midline, paired bones (4)?

Vomer
Ethmoid
Sphenoid
Occiput

26

What happens to the temporal bones with external rotation?

Rotate anteriorly

27

What happens to the squamous portion of the temporal bones with external rotation?

Widen

28

What happens to the mastoid processes as the temporal bones externally rotate?

Move posteromedially

29

True or false: physiologic strain patterns still have bones moving in opposite directions

True

30

True or false: because of the body acting as a unified whole, trauma to another part of the body may also elicit a dysfunction within the cranium

True

31

How are somatic dysfunctions of the cranium named?

By the motions of the bones ("strain pattern")

32

What, technically is a pathologic strain?

Shearing force the causes the anatomic axis to be disrupted

33

What is the axis through which torsions of the skill occur about? What are the two landmarks of the skull that these go through?

-Anterior-posterior
-From the nasion to the opisthion

34

The temporals always move with what other bone?

occiput

35

How are torsions named?

By which greater wing of the sphenoid moves superiorly

36

Can you have a right and a left torsion together?

No

37

What are the physiologic strain patterns?

Torsions and sidebending-rotations

38

How are sidebending rotations named?

For the side of the convexity

39

Can sidebending and rotation of a sidebending rotation be in opposite directions?

No

40

The falx cerebri has what sinus running through it?

Superior sagittal sinus

41

The falx cerebelli has what sinus running through it?

Occipital sinus

42

The tentorium cerebelli has what sinus running through it?

Transverse sinus

43

All three sinuses in the skull come together where?

Straight sinus

44

True or false: the bones of the skull are malleable

True (?)

45

What is the treatment for children with colic? Why does this work?

Tweaking of CN X,

Decompression of the condylar parts
