Cranial III Flashcards
(45 cards)
What are the components of the primary respiratory mechanism? (5)
- Inherent respiratory mech
- Fluctuation of CSF
- Reciprocal tension membrane
- Articular mobility of the cranial bones
- Mobility of the sacrum
What type of treatment is cranial?
MFR
What causes the inherent motility of the CNS?
Glial cells firing, causes the coiling and uncoiling of the ram’s head
What is the reciprocal tension membrane?
Dura
Where does the dura attach to the sacrum?
Anterior portion of S2
What is the rate of the CRI?
6-12 / min
What is sutherland’s fulcrum?
Straight sinus
Review BADNF.
Review
When the midline bones go into flexion, what happens to the paired bones (external or internal rotation)?
External rotation
When the midline bones go into extension, what happens to the paired bones (external or internal rotation)?
Internal rotation
When other plans of motion can the sacrum rotate about with relation to the occiput?
AP or vertical axis
What are the two physiologic strains?
- Torsion
- Sidebending-rotations
What is characteristics about all pathologic strains?
Cause a shearing force that causes the anatomic axis to be disrupted
What are the three major pathologic strains?
- Vertical strain
- Lateral strain
- SBS compression
What is the axis for torsions?
AP
What is the motion of torsions?
Opposite directions
How are torsions named?
Superior greater wing of the sphenoid
The temporal bones move with what other cranial bone? Why is this important?
Occiput
-Mandible swings on temporal bones, thus may be treated
The facial bones move with what other bones?
SBS
True or false: torsions cross midline
False–never cross midline
What are the two axes that are used with sidebending-rotations?
- 2 vertical axes
- AP axis
What produces sidebending rotations?
Lateral force directed exactly at the level of the SBS
True or false: with sidebending-rotations occur, the two motions occur at the same time
True
How do you name sidebending rotations?
For the side of the convexity (the side the proverbial egg falls out of)
