42
Q

What did he think the skull sutures looked like, why do we care?

A

though gills of a fish, meaning should have a primary respiratory movement they are not fully fused, Bull shit!!

43
Q

What is the current view as to what is causing the fluctuation of the CSF?

A

Caused by the tension put on the dura matter between the cranium and sacrum, What is the wave of blood flow in Brain called?

Q

What is the contact of the hand to feel the CRI?

A

contact of hand is very light, feather on the head, hair, skin sub q tissue bone, separated from Respiratory

46
Q

What can Somatic dysfunction do the CRI?

A

diminish amplitude, and cause asymmetric direction, decrease in strength

47
Q

What is the normal direction? (cranial)

A

Longitudinal

48
Q

What is the Sutherland fulcrum?

b. Inhalation, Angle gets increasing inferior (this is Ernie or Stewie)

56
Q

Extension of the SBS joint SBS moves _______ as the distance _______ between the inferior angles of the sphenoid and occiput.

A

a. Extension of the SBS joint SBS moves INFERIORLY as the distance INCREASES between the inferior angles of the sphenoid and occiput, extension is paired with what motion?
b. Exhalation, Angle gets decreasingly inferior, who is extension?
c. Bert or Brian impt. b/c people die with exhalation, thought this is bad?

57
Q

The sphenoid, occiput, ethmoid and vomer have what axis of rotation?

A

a. transverse Axis of rotation

58
Q

What bones of the Cranial Vault rotate externally?

Frontals – Parietals – Temporals • Face - Rotate “Externally” – Maxilla, – Palatines – Zygomae

59
Q

. Where does the spinal dura start and end?

A

a. Starts at foramen magnum and ends at S2

60
Q

. SBS Extension is paired with Sacral?

A

a. Sacral Nodding towards the NUTS!, i.e. sacral base moves anteriorly Remember Extension is NUTS!!!, flexion?
b. Counternutation, i.e. sacral base moves posteriorly, Flexion is Not Nuts!!!

61
Q

. What direction do the wing of the sphenoid bone move with Cranial Sacral Flexion or SBS flexion?

A

. Greater wing moves inferiorly and anteriorly, extension?

b. opposite moves superiorly and posteriorly

62
Q

Through what foramen do each of the cranial nerves exit the cranial vault? (apparently he said know these)

A

Olfactory though Cribriform Plate
Optic though Optic Canal
Oculomotor and trochlear, Trigeminal V1, Abducens thou Superior orbital fissure
Trigeminal V2 thru Foramen Rotundum
Trigeminal V3 thru Foramen Ovale
Facial and Vestbilulochoclear thru Internal Acoustic Meatus
Facial also goes thru facial canal and stylomastoid foramen
5 Principals of PRM
1. The inherent motility mobility of the brain & spinal cord
2. The fluctuation of the CSF
3. The mobility of the intracranial and intraspinal membranes
4. The articulatory mobility of the cranial bones
