What is the “dichotomy” that OMM think exists in regards to cranial?

That there are suture lines that indicate movement blah blah blah solid box

Perfectly

True or false: the articular surfaces are designed for motion, not the result of motion

False– result of motion, not designed for motion

Squamous portion of the temporal bone, between the temporal and parietal bones

What is the primary respiratory mechanism?

How well did you know this?

Not at all

Perfectly

Why is the PRM primary?

Because it is directly concerned with the internal tissue respiration of the CNS

Perfectly

Why is the PRM respiratory?

Because it concerns the physiological function of the interchange of fluids necessary for normal metabolism

How well did you know this?

Perfectly

Why is the PRM a mechanism?

Because all the constituent parts work together as a unit carrying out this fundamental physiology

PRM is the primary motility of what?

CNS

How well did you know this?

Not at all

Perfectly

PRM is the fluctuation of what?

CSF

How well did you know this?

Not at all

Perfectly

The mobility of the PRM is the reciprocal to what?

Tension membrane

What are the three mobilities that the PRM encompasses?

Reciprocal tension membrane
Cranial bones
Sacrum and ilia

What is the difference between motility and mobility?

Motility = Moving on your own

- Mobility - Moved by something else

What causes the CSF pulsations?

Constant rhythm of discharge and recharge and changes in the glial cell size

Also, changes in the size of ventricles

Is there a circulation in the CSF?

No–fluctuation

What is the falx cerebri?

Dural reflection in the sagittal plane between the hemispheres of the cerebrum

What is the falx cerebelli?

Dural reflection in the sagittal plane between the hemisphere of the cerebellum

What is the tentorium cerebelli?

Dural reflection superior to the cerebellum, and inferior to the cerebrum A "diaphragm" according to osteopaths

What is the function of the reciprocal tension membrane?

- Limits motion of the cranial bones | - Slows down movement

The motion of the sacrum in the CS model is about which axis?

Transverse axis at the second sacral ligament

Why does the sacrum move in response to the flow of CSF?

Dural attachment to the sacrum

Where does the dura attach to the sacrum?

Dura attaches to the anterior surface of the sacral canal at the level of S2

What happens to the sacrum with flexion of the head? How does this compare to the respiratory motion?

Posterior motion Opposite of respiratory motion

How many cycles of CSF are there per minute?

6-12

What is the cranial rhythmic impulse?

Fictitious finding of a palpable, rhythmic motion

What are the components of the vault hold?

- Index finger on the greater wings of the sphenoid - 5th finger on the lateral angles of the occiput - Ears between the 3rd and 4th fingers

The sphenoid and occiput move around each other at what anatomic site?

Sphenobasilar synchondrosis

What happens to the bases of the occiput and SBS with flexion? Extension?

Rise in flexion | Fall in extension

What happens to your fingers with extension of the SBS?

SBS flattens, and your fingers come toward you and come together

When the midline bones go into flexion, what happens to the paired bones?

External rotation

When the midline bones go into extension, what happens to the paired bones?

Internal rotation

True or false: there can be more than one strain pattern at once

True

True or false: the same patient can have different strain patterns of any given day

True

What is the occipitomastoid suture?

Suture between the occiput and the mastoid process

What is the external occipital protuberance?

Inion

What is superior temporal line?

Line of bone superior on the parietal bone

What is the difference between internal and external beveling?

Internal is when the bevels are on the inside of the bone External is opposite

What are the five main aspects of the PRM?

- Inherent motility - Fluctuation of CSF - Mobility of RTM - Articular mobility of cranial bones - Articular mobility of the sacrum and the ilia

What is "sutherland's fulcrum"?

Straight sinus

Flexion of the occiput causes what sacral movement? How does this compare to the anatomic way to describe this motion?

Flexion of the head causes the sacral base to move posteriorly. This is terms flexion of the sacrum, while the anatomic term is extension
