|
When originally explored by Sutherland, the sphenoid articulatory junction looked like _____, which gave him an indicator of the potential for motion?
|
gills of a fish
|
|
|
What is the CRI and what do the motions of "inspiration" and "expiration" correspond to within this model?
|
cranial rhythmic impulse or primary respiration.
inspiration corresponds to flexion at the sphenobasilar synchondrosis (SBS) which is the joint between the sphenoid and the occiput expiration corresponds to extension at the SBS |
|
|
* What are the five principles of primary respiration? *
|
1. inherent motility of brain and spinal cord
2. fluctuation of cerebrospinal fluid 3. mobility of membranes 4. articular mobility of cranial bones 5. involuntary mobility of sacrum between ilia |
|
|
How does general motility of CNS manifest?
|
1. there is a neural cord coiling and uncoiling in embryological development
2. when neurons are grown in culture and in vivo there is an observable, pulsating rhythm |
|
|
* What is the relationship between motility and mobility? *
|
Brain tissue and CSF is motile.
Membranes and bones and sacrum are mobile in response to the motility of the CNS. |
|
|
What is a Traube-Hering-Mayer wave?
|
rhythmic variations in blood pressure at 6 to 12 cycles a minute related to variations in vasomotor tone. this completely corresponds to the CRI.
|
|
|
What is the normal CRI rate?
|
8-12
|
|
|
What type of tissue is found between the cranial sutures?
|
dura mater
|
|
|
What does combining the tensegrity model with the cranial membranes translate to in terms of motion?
|
the membranes distribute any force at any point in the cranium to all other points where that membrane is attached. this was named by Sutherland as the Reciprocal Tension Membrane (RTM).
|
|
|
What is the correlation between suture closure and age?
|
none. suture closure is related to other global osteopathology.
