Cranial Intro Flashcards
1
Q
5 PRM anatomical-physiological elements?
A
- inherent motility of the brain and spinal cord
- fluctuation of CSF
- mobility of intracranial and intraspinal membranes
- articular mobility of cranial bones
- monbility of sacrum interdependent with motion of SBS
2
Q
Indications for OCMM?
A
- stress
- after birth
- trauma
- dentistry/TMJD
- feeding difficulities infant
- plagiocephaly
- vertigo
- TBI/concussion
- orofacial pain
- sinusitis/otitis media
- tinnitus
- post CVA
- torticollis
3
Q
Absolute contraindications to OCMM?
A
- Acute CVA or intracranial bleed
- Acute skull fracture
4
Q
Relative contraindications to OCMM?
A
- hx of siezures
- coagulopathy
- Increased ICP
5
Q
Where is CSF produced?
A
choroid plexus of 3rd and 4th ventricles
6
Q
What is the driving push from CSF expansion called?
A
Cranial rhythmic impulse
7
Q
What are the motion characteristics of the CRI and describe them?
A
- Rate
- 8-14
- Rhythm
- Amplitude
- SD will decrease this
- Direction
- normal should be linear and symmetric
- Strength
8
Q
What is the reciprocal tension membrane?
A
- functioning unit that holds bones of the vault and base under a constant tension
- this is made by the tentorium cerebelli and the falx
- allows but limits motion and acts as a spring storing energy in flexion and releasing in extension
9
Q
Where does the RTM attach?
A
- frontal
- sphenoid
- temporal
- occipital
10
Q
Describe cranial flexion.
A
- SBS rises superiorly decreasing the angle btw the occiput and the sphenoid
- The head widens and decreases the AP diameter becoming more spherical
- inhalation (head fills like a balloon becoming spherical with cranial inhalation/flexion)
11
Q
Describe cranial extension?
A
- SBS moves inferiorly increasing the distance btw the inferiro abgle of sphenoid and occiput
- Head gets tall and narrow (paired with exhalation)
- people die with exhalation, face elongates and cheekbones are prominent
- exhalation=extension
12
Q
Where does the dura attach on the skull and sacrum?
A
- foramen magnum to the posterior body and disc of S2 in the spinal canal
13
Q
What does sacral nutation pair with?
A
SBS extension
base moves anteroinferior and apex moves posterior
14
Q
What does counternutation pair with?
A
- SBS flexion
- base moves posterosuperior and apex moves anterior
15
Q
Where does CN1 travel?
A
Cribiform plate
