Savarese chapter 9 (cranial) Flashcards
The primary respiratory mechanism =
CNS + CSF + Dural Membranes + Cranial Bones + Sacrum
Who made up cranial?
Sutherland
Cranial Rhythmic Impulse
10-14 cycles per minute
Factors that will decrease the CRI
- Stress (emotional or physical)
- Depression
- Chronic fatigue
- Chronic infections
Factors that will increase the CRI
- Vigorous physical exercise
- Systemic fever
- Cranial OMT
Dural attachments
Foramen magnum
C2
C3
S2
Reciprocal Tension Membrane
The inelastic rope/meninges
Craniosacral Flexion
Midline bones flex
Sacral base posterior (counternutation)
Decreased AP diameter
External rotation of the paired bones
Craniosacral Extension
Midline bones extend
Sacral base anterior (nutation)
Increased AP diameter
Internal rotation of the paired bones
Torsion
1 AP axis
The sphenoid & occiput rotate in opposite directions
Named for the superior GWS
Sidebending-Rotation
The sphenoid & occiput rotate in the same direction around 1 AP axis
The sphenoid & occiput rotate in opposite direction about 2 vertical axes
Named for the side of convexity (side that widens/bones get further apart)
Vertical Strain
The sphenoid & occiput rotate in the same direction about 2 parallel transverse axes
Named for the direction of sphenoid movement.
Lateral Strain
“parallelogram head”
The sphenoid & occiput rotate in the same direction about 2 parallel vertical axes.
Named for the deviation of the base of the sphenoid
SBS compression
Sphenoid & occiput have been pushed together
Midline Bones
Sphenoid Occiput Sacrum Ethmoid Vomer
CN I exits the skull via the
Cribiform plate
CN II exits the skull via the
Optic canal
CN III exits the skull via the
Superior Orbital Fissure
CN IV exits the skull via the
Superior Orbital Fissure
