What are some important historical points about William Garner Sutherland, DO (WGS) 1873-1954- OCMM?
- Observed a Beauchene skull
- thought temporal and parietal bones resemled gills of fish
- Started OCMM techniques
- sphenoid bone beveled like gills of a fish
Who quoted:
ʻBeveled, like the gills of a fish, indicating articular mobility for a respiratory mechanism.ʼ
William G. Sutherland, DO
Other than William Sutherland, who was encourage by A.T. Still to study the circulation from the head through the spinal cord and its return
- Favored radiographic study, followed by a single adjustment
- was a neuropsychiatrist
Charlotte Weaver, DO
What is the fundamental aspect of the classical cranial osteopathic model?
Primary respiratory mechanism
Explan the meaning behind each of the words of:
Primary Respiratoy Mechanism
primary because precedes the thoracic respiration in importance
respiratory because of the exchange of gases and metabolites at the cellular level
mechanism because it is an integrated machine, each par working in relationship together
The components of which mechanism are from the basis of an inherent rhythm that can be palpated on the skull and throughout the body?
Primary Respiratory Mechanism
The primary respiratory mechanism is believed to occur dependently with/ independently of cardiac and respiratory activity and at a slightly slower/faster rhythm than pulmonary breathing
independently of
slower
How many anatomic-physiologic components are involved with the primary respiratory mechanisms?
Phenomenon of osteopathic cranial manipulative medicine?
5
What is the integration of anatomic structure and physiologic processes and can be palpated?
OCMM and primary respiratoy mechanism
What are the 5 phenomenon of the osteopathic cranial manipulative medicine?
1) . Inherent Rhythmic Motility of the Brain and Spinal Cord
2. Fluctuation of the Cerebrospinal Fluid
3. Mobility of Intracranial and Intraspinal Membranes (Reciprocal Tension Membrane: RTM)
4. Articular Mobility of the Cranial Bones
5. Involuntary (Respiratory) Mobility of the Sacrum Between the Ilia
The first phenomenon of osteopathic cranial manipulative medicine?
1). Inherent Rhythmic of the Brain and Spinal Cord
1). Inherent Rhythmic Motility of the Brain and Spinal Cord
What is the difference between motility and mobility?
mobility= able to move something else, stays put (cilia, flagella)
motility= move independently
Second PHENOMENA OF OSTEOPATHIC CRANIAL MANIPULATIVE MEDICINE
- of the Cerebrospinal Fluid
- Fluctuation of the Cerebrospinal Fluid
the thirds PHENOMENON OF OSTEOPATHIC CRANIAL MANIPULATIVE MEDICINE
- of Intracranial and Intraspinal Membranes (Reciprocal Tension Membrane: RTM)
(dural membranes)
- Mobility of Intracranial and Intraspinal Membranes (Reciprocal Tension Membrane: RTM)
4th PHENOMENON OF OSTEOPATHIC CRANIAL MANIPULATIVE MEDICINE:
- Articular of the Cranial Bones
- Articular Mobility of the Cranial Bones
5th PHENOMENON OF OSTEOPATHIC CRANIAL MANIPULATIVE MEDICINE:
- Involuntary (Respiratory) of the Sacrum Between the Ilia
- Involuntary (Respiratory) Mobility of the Sacrum Between the Ilia
Review the factors involved in cranial motion:
1).The Inherent Motility of the Brain and Spinal Cord
- Subtle, , pulse-wavelike movement
- Shortens and thickens () and lengthens and thins ()
- This may be a of the motion of embryologic development or a reflection of glymphatic drainage
slow
coils; uncoils
continuation
How many phases involved with the Inherent Motility of the Brain and Spinal Cord, which is the first phenomena of the OCMM?
biphasic
Shortens and thickens (coils) and lengthens and thins (uncoils)
2).Fluctuation of Cerebrospinal Fluid
- CSF, produced by the , is inside and outside the CNS bathing it and protecting it.
- Fluctuation: wavelike motion of fluid in a body cavity observed by or percussion.
- In the PRM model as the CNS shortens and lengthens, the change shape and the CSF fluctuates.
- This manifests a change throughout the body
choroid plexuses
palpation
ventricles
hydrodynamic
How much CSF fluid is produced daily?
500 ml
How often is the CSF fluid replaced daily?
2-4X daily
How much CSF fluid usually at one time?
150 ml
Which 4 places and by what structure produces CSF?
70% lateral, 3rd, 4th ventricles
30% formed as CNS extracellular fluid moves into the subarachnoid space
Describe the path of the CSF?
lateral ventricle
3rd ventricle
cerebral aquecuct
4th ventricle
cisterna magna
subarachnoid space
arachnoid villi
large sagittal venous sinus and other venous sinuses
The CSF exits the 4th ventricle @
(1) midline via the foramen of Magendie
(2) lateral foramina of Luschka
enters the cisterna magna
Where is the cisterna magna located?
behind medulla and under cerebellum
The cisterna magna, which is behind the medulla and beneath the cerebellum, is continuous with what?
subarachnoid space that surrounds the brain and spinal cord
What are some Fluctuating Waveforms Within the Body?
Cardiac depolarization
⧫ Respiration
⧫ Peristalsis
⧫ Lymphatic
⧫ Glymphatic (cranial lymphatics)
⧫ CRI/PRM
perivascular tunnels formed on astroglial cells that promotes elimination of proteins and metabolites from the CNS
glymphatic system
As the brain lacks evidence of lymphatic circulation, what is the theory of how the brain clears extracellular proteins?
glymphatic system
How is it theorized how solutes from the brain iterstitium move from the parenchyma to the CSF?
glymphatic system
A substantial portion of subarachnoid cycles through the brain interstitial space.
CSF
