What are the 2 motions of the midline cranial bones?
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?
In craniosacral flexion the SBS moves ________.
In craniosacral flexion the sacrum moves?
Posterior (aka counternutation)
In craniosacral flexion what is the associated phase of respiration?
In craniosacral flexion which direction do the paired bones move?
What occurs to the AP diameter in craniosacral flexion?
In craniosacral extension the SBS moves in which direction?
In craniosacral extension the sacrum moves which direction?
Anterior (aka nutation)
In craniosacral extension what is the associated phase of respiration?
*Extension = Exhalation
In craniosacral extension which direction do the paired bones move?
What occurs to the AP diameter in craniosacral extension?
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
*Pic shows left cranial torsion
For cranial sidebending/rotation SD's what is the coupling (sphenoid/occiput), naming, and axis?
- Coupling: sphenoid and occiput rotate SAME and sidebend OPPOSITE
- Naming: the convexity in sidebending
- Axis: (2) vertical axes and (1) AP-axis
*Pic shows left sidebending/rotation SD
For cranial vertical strains what is the coupling (sphenoid/occiput), naming, and axis?
- Coupling: sphenoid and occiput rotate same direction about 2 transverse axes (i.e., flexion at the sphenoid coupled with extension at the occiput)
- Named: SBS translation
- Axis: (2) Transverse Axis
For cranial lateral strain what is the coupling (sphenoid/occiput), naming, and axis?
- Coupling: sphenoid and occiput spin in same direction about each vertical axis
- Named: SBS translation (also can name for which wing is higher = highest corner of the parallelogram)
- Axis: (2) Vertical Axes
A parallelogram head is associated with what type of cranial SD?
Which 4 fingers are used in the vault hold and where is each finger placed?
1) Index finger --> greater wings of the sphenoid
2) Middle finger --> temporal bone (in front of ear)
3) Ring finger --> mastoid process of temporal bone
4) Pinky finger --> squamous portion of occiput
What is the CV4 used for?
What are the 4 attachments for the Dura?
3) Foramen Magnum
