Cranial II Flashcards

1
Q

What are the five components of the primary respiratory mechanism?

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

Q

What is the cranial rhythmic impulse? What causes it?

A

Palpable, rhythmic fluctuations brought about by the PRM

Glial cells firing–not breathing movements

Q

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

Q

How can you influence the CSF tide?

A

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

Q

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

A

Internal rotation

20
Q

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

A

Flexion

21
Q

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

A

Through the petrous ridge

Converge as they move anteriorly

22
Q

What is the reciprocal tension membrane?

A

The dura mater

23
Q

What is the normal rate of the CRI?

A

6-12 per minute

24
Q

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

A

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

25
Q

What are the midline, paired bones (4)?

A

Vomer
Ethmoid
Sphenoid
Occiput

26
Q

What happens to the temporal bones with external rotation?

A

Rotate anteriorly

27
Q

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

A

Widen

28
Q

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

A

Move posteromedially

29
Q

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

A

True

30
Q

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

A

True

31
Q

How are somatic dysfunctions of the cranium named?

A

By the motions of the bones (“strain pattern”)

32
Q

What, technically is a pathologic strain?

A

Shearing force the causes the anatomic axis to be disrupted

33
Q

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

A
  • Anterior-posterior

- From the nasion to the opisthion

34
Q

The temporals always move with what other bone?

A

occiput

35
Q

How are torsions named?

A

By which greater wing of the sphenoid moves superiorly

36
Q

Can you have a right and a left torsion together?

A

No

37
Q

What are the physiologic strain patterns?

A

Torsions and sidebending-rotations

38
Q

How are sidebending rotations named?

A

For the side of the convexity

39
Q

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

A

No

40
Q

The falx cerebri has what sinus running through it?

A

Superior sagittal sinus

41
Q

The falx cerebelli has what sinus running through it?

A

Occipital sinus

42
Q

The tentorium cerebelli has what sinus running through it?

A

Transverse sinus

43
Q

All three sinuses in the skull come together where?

A

Straight sinus

44
Q

True or false: the bones of the skull are malleable

A

True (?)

45
Q

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

A

Tweaking of CN X,

Decompression of the condylar parts
