List the five components of the primary respiratory mechanism theory |
1. Motility of the brain & spinal cord 2. Fluctuation of Cerebrospinal fluid 3. Mobility of the intracranial & Intraspinal Membranes 4. Mobility of the Cranial bones 5. Involuntary mobility of the Sacrum between the ilium |

|
Describe the importance & location of the sphenobasilar synchondrosis (SBS) |
Importance: Ask Shaun :)
No really: all cranial base strains are described by the motion of the SBS
Location: Yup.
|
|
|
Describe the normal movement of the sphenobasilar synchondrosis (SBS)
[2 words] |
Flexion Extension |
|
|
Describe the flexion of the sphenobasilar synchondrosis (SBS) |
In FLEXION when the SBS rises superiorly the sphenoid and occiput rotate in opposite directions about 2 parallel transverse axes |
|
|
Describe FEEL of flexion of the sphenobasilar synchondrosis (SBS) |
1. the occiput expands inferiorly and widens
2. the greater wings of the sphenoid (just behind the zygomatic arch) move inferiorly and widens. |
|
|
Describe the Extension of the sphenobasilar synchondrosis (SBS) |
In EXTENSION, the SBS moves inferiorly and the sphenoid and occiput rotate in opposite directions about 2 parallel transverse axes |
|
|
Describe FEEL of extension of the sphenobasilar synchondrosis (SBS) |
1. the occiput moves superiorly and gets thinner.
2. the greater wings of the sphenoid move superiorly and get narrower |
|
|
List the 3 physiological cranial base strain patterns |
Flexion/Extension Torsion Sidebending rotations |
|
|
Describe a Flexion/Extension cranial base strain pattern |
Axis: 2 parallel transverse axes Sphenoid & Occiput rotate in Opposite Directions
Flexion: SBS moves superiorly Extension: SBS moves inferiorly |
|
|
Describe a Torsion cranial base strain pattern |
Axis: 1 AP axis Sphenoid & Occiput rotate in Opposite directions
Named: which greater wing of the sphenoid is superior
Feel: Vault Hold - one index finger moves anteriorly [toward pt's nose] feels like unscrewing a jar lid |
|
|
Describe a Sidebending Rotation cranial base strain pattern |
Right & Left Axis: 1 AP - sphenoid & occiput rotate in same direction 2 parallel vertical - Occiput & Sphenoid sidebend in opposite directions
Named for convexity [bulge] Feel: vault hold - down & out sensation [cracking an egg] |
|
|
List the 3 non-physiological cranial base strain patterns |
Vertical Strain Lateral Strain SBS compression |
|
|
Describe a Vertical Strain cranial base strain pattern |
Axis: 2 parallel vertical axes Sphenoid & Occiput rotate in the same direction Named: for location of the sphenoid base in relation to occipital base |
|
|
Describe a SBS Compression cranial base strain pattern |
Little or no motion at SBS
"Bowling ball head" or "bag of worms" |
