Q

What is PRM?

What is PRM definition?

A

Primary Respiratory Mechanism -what makes the bones move.
Primary - main internal tissue process of metabolism.
Respiratory - exchange of gases.
Mechanism - movement of tissue and fluid for a purpose.

Q

Basic tenants of the classical cranial model.

A

A. Inherent MOTILITY of the CNS.
B. PLASTICITY and ELASTICITY of the intracranial and intraspinal membranes.
C. Fluctuation of the CSF.
D. Articular mobility and involuntary motion of the CRANIAL BONES.
E. Articular mobility and involuntary motion of the SACRUM between the ilia.

17
Q

Four main fontanelles

A

Bregma
Lambda
Asterion
Pterion

18
Q

Difference between motility and mobility

A

Mobility - requires something else to move it

Motility - inherent ability to move

19
Q

Why does sacrum move?

A

Dural attachment to sacrum at S2.

20
Q

Structures of the PRM

A

Brain/SC
CSF
Intracranial membranes
Articular mechanism of cranial bones.

21
Q

Dynamic relations of the PRM:

Bone mobility is related to and controlled by what?

A

The reciprocal tension membrane.

cranial and spinal dura, falx cerebri and cerebelli, tentorium cerebelli

22
Q

what is the motor for the PRM?

A

the brain

23

CRI - definition

What is it?

A 
Cranial Rhythmic Impulse
The PALPABLE (not visible) expression of primary respiratory mechanism.
