Lecture 2: Intro to OCMM Flashcards
What year was the Osteopathic Cranial Academy established by students of Dr. Sutherland?
1947
What year was Dr. Sutherland’s work first published in the JAOA?
1944
What are the 5 components of the Primary Respiratory Mechanism (PRM)?
- The inherent mobility of the brain and spinal cord
- The fluctuation of the CSF
- The mobility of the intracranial and intraspinal membranes
- The articulatory mobility of the cranial bones
- The involuntary mobility of the sacrum between the ilia
The inherent mobility of the brain/SC as one of the components of PRM/OCMM is due to what 2 factors?
Which can be measured?
- Traube-Hering Wave due to changes in blood flow velocity and is measureable by laser flowmetery
- Glial cells contribute to neurovascular coupling and regulate flow in the brain
What is the normal range of the CRI?
6-14 cycles/min
The CRI is separate from which physiologic mechanisms?
- Respiratory
- Circulatory
What is the “Sutherland Fulcrum”?
Location?
A point of function generally located in the region of the straight sinus (junction of the Falx and Tentoria)
The Reciprocal Tension Membrane (RTM) is created by what 3 components?
- Tentorium
- Falx Cerebri
- Cerebellum
Reciprocal Tension Membrane (RTM) attaches to the bones of the vault and base, holding them under?
Constant tension
Does the RTM allow for motion?
Allows BUT limits motion
What is the Anterior/Superior pole of attachment for the RTM?
Crista galli
What is the Anterior/Inferior pole of attachment for the RTM?
Clinoid processes of Sphenoid
What is the Lateral pole of attachment for the RTM?
Mastoid angles of parietals AND petrous ridges of temporal bones
What is the Posterior pole of attachment for the RTM?
Internal occipital protuberance AND transverse ridges
What are the 2 most important components of the PRM?
1) The inherent mobility of the brain and spinal cord
2) Fascial mobility and continuity significantly impacts the RPM
