Cranial High Yield Flashcards
What are the 2 motions of the midline cranial bones?
1) Flexion
2) Extension
What are the midline cranial bones vs. paired cranial bones?
- Midline (SOVE) = Sphenoid, Occiput, Vomer, Ethmoid
- Paired = all the others
What are the 2 motions of the paired cranial bones?
1) IR
2) ER
In craniosacral flexion the SBS moves ________.
Cephalad
In craniosacral flexion the sacrum moves?
Posterior (aka counternutation)
In craniosacral flexion what is the associated phase of respiration?
Inhalation
In craniosacral flexion which direction do the paired bones move?
ER
What occurs to the AP diameter in craniosacral flexion?
Shortens
In craniosacral extension the SBS moves in which direction?
Caudad
In craniosacral extension the sacrum moves which direction?
Anterior (aka nutation)
In craniosacral extension what is the associated phase of respiration?
Exhalation
*Extension = Exhalation
In craniosacral extension which direction do the paired bones move?
IR
What occurs to the AP diameter in craniosacral extension?
Lengthens
What are the 3 non-physiologic SD’s associated w/ the cranium?
1) Vertical strains
2) Lateral strains
3) SBS Compressions
For cranial torsions what is the coupling (sphenoid/occiput), naming, and axis?
- Coupling: sphenoid and occiput rotate opposite
- Named: HIGHER wing of sphenoid
- Axis: AP-axis
