1
Q

Five components of PRM

A

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

2
Q

Contributors to cranial motion

A

Traube-Hering Wave - due to changes in blood flow velocity

Glial cells

3
Q

Motion Characteristics fo CRI

A
Rate - 10-14
Rhythm - regular, like ocean tide
Amplitude - SD may diminish
Direction - longitudinal and symmetric
Strength - SD may diminish
4
Q

Sutherland Fulcrum

A

functional name given the straight sinus as the origin of the 3 sickle-shaped agents of the falx cerebri and the tentorium cerebelli

5
Q

Reciprocal Tension Membrane

A
the meninges(tentorium, falx cerebri, and cerebellum) and the cord constitute a link between the cranium and the sacrum
holds bones of vault and base under constant tension
allows but limits motion
6
Q

Main Poles of Attachment

A

Anterior/superior pole - crista galli
anterior/inferior pole - clinoid processes of sphenoid
lateral pole - mastoid angles of parietals and petrous ridges of temporal bones
posterior pole - internal occipital protuberance and transverse ridges

7
Q

Sutures

A
Coronal
Sagittal
Parietosquamous
Spenosquamous
temporozygomatic
lambdoidal
occipitomastoid
*pterion and asterion, bregma and lambda
8
Q

SBS

A

Sphenobasilar Symphysis

where the basisphenoid and basiocciput join to form a synchondrosis

9
Q

SBS Flexion

A

SBS - moves superiorly
Occipital squama moves - posteriorly and inferiorly
greater wing moves - anteriorly and inferiorly
paired with inhalation

10
Q

SBS Extension

A

SBS - moves inferiorly
Occipital squama moves - anteriorly and superiorly
greater wing moves - posteriorly and superiorly
paired with exhalation

11
Q

CN I

A

cribriform plate

12
Q

CN II

13
Q

CN III

A

superior orbital fissure

14
Q

A

superior orbital fissure

15
Q

CN V

A

V1 - superior orbital fissure
V2 - foramen rotundum
V3 - foramen ovale

16
Q

CN VI

A

superior orbital fissure

17
Q

CN VII

A

internal acoustic meatus
facial canal
stylomastoid foramen

18
Q

CN VIII

A

internal acoustic meatus

19
Q

Attachment of dura to sacrum

A

posterior aspect of S2

respiratory axis

20
Q

Axis of nutation and counternutation

A

MT (postural axis)

anterior aspect fo S2

21
Q

Nutation

A

nodding of base anteriorly
apex moves posteriorly and superiorly
paired with extension

22
Q

counternutation

A

base moves posteriorly
apex moves anteriorly and inferiorly
paired with flexion
