Osteopathy in the Cranial Field Flashcards
dynamic unit of function
neural system continuous
CT continuous
fluids continuous
Dr. Sutherland
looked at skull
- like gills of fish
- mobility for respiratory mechanism
skull bones beveled
like gills of fish
squamoparietal suture
nicely beveled
primary respiratory mechanism
primary - underlying all physio functions
respiratory - cellular respiration
mechanism - cranial articulations
5 tenets of PRM
1 - flucuations of CSF and potency of tide
2 - mobility of intracranial and intraspinal membranes, and function of reciprocal tension membrane
3 - inherent mobility of CNS
4 - articular mobility of cranial bones
5 - involuntary mobility of sacrum between the ilia
1st tenet of PRM
flucuations of CSF and potency of tide
circulation and flucuation
- 70% choroid plexi
- 30% CSF extracellular fluid moves into subarachnoid space
foramen of magendie and luschka
intraventricular and subarachnoid space connections
pacchionian granulations
arachnoid
-channels for CSF to venous flow
cranial rhythmic impulse
CSF fluctuation two characteristics:
1. physical potency/energy that acts through body (hydrodynamic mechanism)
- electrical potential acting in positive and negative phases
fluid flow AND electrical property
rate of CRI**
occurs 10-14 cycles per minute in normal adults
second tenet of PRM
mobility of intracranial and intraspinal membranes and function of reciprocal tension membrane
-dura mater to straight sinus
sutherland fulcrum
straight sinus
-origin of the dura
reciprocal tension membrane
function:
-partition, support, shock absorb, stress-meeting
dura
continuous with periostium of calvarium
-forms falxes and tentorium
attachments of falx cerebri
- crista galli of ethmoid
- frontal bones along metopic suture
- parietal bone along sagittal suture
- occiput
- tentorium cerebelli
