DSA: Intro to OCMM

Question 1

What are the five components of PRM?

Answer 1

Question 2

What causes the Traube-Hering Wave?

Answer 2

changes in blood flow velocity

glial cells may support cranial motion (both structurally + physiologically though regulating blood flow)

Question 3

What is the average cranial rhythmic impulse? how do you palpate it?

Answer 3

10-14 cycles/minute

light touch, relaxed

remember: CRI is separate from resp/circ phys, but it is influenced by them

Question 4

What are the main poles of attachment of the Reciprocal Tension Membrane?

Answer 4

Question 5

SBS Flexion vs. Extension

Answer 5

Extension paired with Exhalation

Flexion paired with Inhalation

Question 6

What causes the involuntary mobility of the sacrum?

Answer 6

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

Question 7

What are the axes of motion of the sacrum? Which is related to PRM in OCMM?

Answer 7

1. ST (Respiratory) Axis
2. MT (Postural) Axis
3. IT (Pelvic/Ilial) Axis

Question 8

_____ of the sacrum is matched with SBS ____.

Answer 8

Nutation of the sacrum is matched with SBS Extension

(basically exhalation goes with exhalation)

Question 9

During a research study, it was found that there wsa a change in respiration, BP, and CSF pressure when what occured?

Answer 9

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)

Question 10

Study Question:

Define: Pterion, Asterion, Bregma, Lambda

Answer 10

1. Pterion: region where the frontal, parietal, temporal, and sphenoid bones join together
2. Asterion: point on the skull corresponding to the posterior end of the parietomastoid suture.
3. Bregma: point or area of the skull where the sagittal and coronal sutures joining the parietal and frontal bones come together.
4. Lambda: midpoint of the curve of best fit along the lambdoid suture

Question 11

Study Question:

What are the main cranial sutures?

Answer 11

Question 12

Study Question:

What is SBS?

Answer 12

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.

Question 13

Study Question:

What foramen do all the CNs exit?

Answer 13

Question 14

Study Question:

ID falx cerebrai, falx cerebelli, tentorium cerebelli

Answer 14

Question 15

Study Question:

Who is credited for OCMM? Discuss his reasonings

Answer 15

Dr. Sutherland

Question 16

Study Question:

What is the significance of the Ernie and Bert head style?

Answer 16
