Q

For cranial sidebending/rotation SD’s what is the coupling (sphenoid/occiput), naming, and axis?

A
  • 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

17
Q

For cranial vertical strains what is the coupling (sphenoid/occiput), naming, and axis?

A
  • 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
18
Q

For cranial lateral strain what is the coupling (sphenoid/occiput), naming, and axis?

A
  • 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
19
Q

A parallelogram head is associated with what type of cranial SD?

A

Lateral strain

2) Middle finger –> temporal bone (in front of ear)
3) Ring finger –> mastoid process of temporal bone
4) Pinky finger –> squamous portion of occiput
