Cranial III Flashcards
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)
What are the axes involved with vertical strains?
2 transverse
What is the direction for vertical strain patterns?
Same
How are vertical strain patterns named?
Direction of the base of the SBS
What happens to the 2nd and 5th fingers with a superior vertical strain?
2nd = move inferiorly
5th = move superiorly
What happens to the temporal bones with a superior vertical strain?
Temporals move into internal rotation–follow the occiput
What happens to the temporal bones with an inferior vertical strain?
Temporals move into external rotation–follow the occiput
What are the axes involved with lateral strains?
2 vertical
What is the movement for lateral strains?
Same
How are lateral strains named?
Base of the sphenoid moves left or right
What causes SBS compressions?
Traumatic blows to the nose, directly in line with the SBS
What is the axis that SBS compressions happen in?
AP
What is the movement of SBS compressions?
Little movement is felt–prevents flexion/extension
What will happen to the fingers with a SBS compression?
Approximation of the index and pinky
What is the indication for a parietal lift?
HA at the vertex
How can you think of internal and external rotation of the parietal bones?
Think of a vector pointing inferiorly at the inferior edge of the suture
What is the basic principle that is used with the frontal lift? What happens to the frontal bones?
Internally rotates the frontals to disengage them from their related bones
Permit them to externally rotate and widen
What are the two roles of the CV-IV compression?
Stimulate the body’s therapeutic potency to heal
stimulates prostaglandins to assist in myometrial contractility–PAST their due dates
True or false: you never do any cranial technique with head trauma patients
True
What is the purpose of the v spread?
Release any stuck sutures
Why would you use the VSD?
Sinusitis, rhinitis, migraines
What is the purpose of temporal rocking?
Temporarily reduce or increase the CRI in anxious patients
