Q

What is the Reciprocal Tension Membrane (RTM)?

A

The dura. it is inelastic - and due to its connections combined with the inherent motility of the CNS - you get cranial bone motion

Q

What motions and through which axis do we find in Sidebending/Rotation?

A

Rotation: through AP axis through the SBS
Sidebending occurs about two parallel vertical axes - one axis passes through foramen magnum and the other through the center of the sphenoid.

24
Q

What happens in a Vertical Strain?

A

Is present when the sphenoid deviates cephalad (superior vertical strain) or caudad (inferior vertical strain) in relation to the occiput.

A

Right lateral strain

28
Q

What axis are present in lateral strain patterns?

A

two vertical axis:
one through the center of the sphenoid
Other through foramen magnum

29

Q

What is the goal of craniosacral treatment?

A

…. is to reduce venous congestion, mobilize articular restrictions, balance the SBS and enhance the rate and amplitude of the C.R.I.

45
Q

What is the purpose of the venous sinus technique?

A

To increase venous flow through the venous sinuses (responsible for 85-95% of drainage from cranium into jugular) so that blood may exit the skull through the jugular foramen.
