DSA: Intro to OCMM Flashcards
What are the five components of PRM?
What causes the Traube-Hering Wave?
changes in blood flow velocity
glial cells may support cranial motion (both structurally + physiologically though regulating blood flow)
What is the average cranial rhythmic impulse? how do you palpate it?
10-14 cycles/minute
light touch, relaxed
remember: CRI is separate from resp/circ phys, but it is influenced by them
What are the main poles of attachment of the Reciprocal Tension Membrane?
SBS Flexion vs. Extension
Extension paired with Exhalation
Flexion paired with Inhalation
What causes the involuntary mobility of the sacrum?
physical extension of the influence of the PRM by way of spinal dura mater
Flexion/extension of the occiput (due to PRM) creates tractional forces upon dura that is translated to the sacrum
What are the axes of motion of the sacrum? Which is related to PRM in OCMM?
- ST (Respiratory) Axis
- MT (Postural) Axis
- IT (Pelvic/Ilial) Axis
_____ of the sacrum is matched with SBS ____.
Nutation of the sacrum is matched with SBS Extension
(basically exhalation goes with exhalation)
During a research study, it was found that there wsa a change in respiration, BP, and CSF pressure when what occured?
external pressure was added to the temporal bones
was NOT seen when external pressure was added to sagittal suture (though still causes lateral and rotational movement at partietal bones)
Study Question:
Define: Pterion, Asterion, Bregma, Lambda
- Pterion: region where the frontal, parietal, temporal, and sphenoid bones join together
- Asterion: point on the skull corresponding to the posterior end of the parietomastoid suture.
- Bregma: point or area of the skull where the sagittal and coronal sutures joining the parietal and frontal bones come together.
- Lambda: midpoint of the curve of best fit along the lambdoid suture
Study Question:
What are the main cranial sutures?
Study Question:
What is SBS?
Sphenobasilar Symphysis
The SBS is where the basisphenoid & the basiocciput join to form a synchondrosis. A synchondrosis is an almost immovable joint between bones bound by a layer of cartilage.
Study Question:
What foramen do all the CNs exit?
Study Question:
ID falx cerebrai, falx cerebelli, tentorium cerebelli
Study Question:
Who is credited for OCMM? Discuss his reasonings
Dr. Sutherland
