What is the overall concept of the medullary lock?
-the medulla stays in the center of the foramen magnum and spinal canal space
-there are 10 known external mechanisms and 1 internal
What do we rely on more for our upper cervical care when someone is having a cicatrix effect?
-holding the adjustments will allow them to start healing and their function should be improving once the subluxation is clear and held
-it is especially great when they reach maintenance care
How do we assess the integrity of the spinothalamic tract in our spinal analysis?
skin temp differential analysis (tytron)
Please list the 10 external locking mechanisms
1) dural attachment to the posterior arch of C1/C2
2) dural attachment to the foramen magnum
3) RCP minor tissue bridge attachment to dura (myodural bridge)
4) RCP major tissue bridge attachment to dura (myodural bridge)
5) inferior oblique tissue bridge attachment to dura (myodural bridge)
6) ligamentum nuchae attachment continues from the midline between the nuchal ligament and the posterior spinal dura at the AO and AA intervals
7) “to be named ligament” arises from tissue of posterior border of nuchal ligament, projected anteriorly and superiorly to enter AA interspace
8) craniale durae matris spinalis ligament is located between the dura mater and posterior border of the AO joints, the edge of foramen magnum, atlas posterior arch, and base of the SP and laminae of C2
9) vertebrodural ligament at the posterior aspect of the cervical dura mater to the posterior wall of the spinal cord at the level of atlas to axis
10) dural attachment to ligamentum flavum
Explain the concept of the cicatrix effect
-it is a major effect compared to the prenumbra effect
-it is scar tissue formation, most commonly found at the dentate ligament
-with subluxations, soft tissue will close in on the spinal cord and impinge it, overtime causing damage
-if the subluxation is corrected, then there will be a primary effect ro breakdown scar tissue slowly in vital areas and then after the person will start to regain the health they want
What are the 2 neurological tracts we covered in the medullary lock?
spinocerebellar and spinothalamic tract
How do we assess the integrity of the spinocerebellar tract in our spinal analysis?
leg length inequality assessment (leg checks)
Explain the concept of the prenumbra effect. What is the main component in our anatomy that is linked with this effect?
-consistent tension on the medulla by the dentate ligaments can disrupt the blood supply to the spinal cord and medulla
-tension/pressure on the dentate ligaments can cause the pial venous plexus to collapse
-restoration of blood flow after an adjustment can have miracle effects
What is the internal locking mechanism? What is the connection of the internal lock to the inferior brainstem/spinal cord?
-dentate ligament goes from the dura to the pia
-dentate ligaments are super tough and hold the cord in place, but if theres a subluxation then the circular shape of cord will become football shaped and lose integrity
-this is a direct impact of issues bc the dentate ligament of C1 is the largest and most horizontal of all the spine
What is the purpose of the external locking mechanisms- as in why do we mention them and how do they affect the inferior brainstem and spinal cord when damaged?
-external locking mechanisms are our static stabilizers
-they hold/lock the area in place
-if they ever get damaged, then they will go against the area that they are supposed to protect
T/F: lines of drive for upper cervical set-ups will always include L->M
true
Place the steps for seated palpation of the posterior arch in the correct order
-locate the EOP
-mark the locations of the C2 LPJ and occipital shelf
-locate the posterior arch in between your finger markings
-locate the C2 spinous and palpate the LPJ adjacent to it
-locate the EOP
-locate the C2 spinous and palpate the LPJ adjacent to it
-mark the locations of the C2 LPJ and occipital shelf
-locate the posterior arch in between your finger markings
The AO joint moves in a ____________ fashion. This word is specific to the AO joint
curvilinear
If the dens is in line with the center of the foramen magnum while the spinous is to the right of the center, what is this listing?
BPSR
The only way to correct the 2nd letter in an atlas listing is by using __________
torque
Please explain the difference between C2 BPSR and PRI listings
BPSR- the body of C2 is the pivot reference point that stayed in the foramen magnum, the spinous has moved to the right so that contact point would be the right spinous
PRI- looks the same as a BPSR but PRI will have extra inferiority compared to BPSR
For an ASRA knee chest set up the doctor needs to have __________ pivot
a 45 degree
Contact points for superior listings are on the __________ of the posterior arch, while the inferior listings are on the _________ of the posterior arch
bottom, top
Inferior elbows should be at what level for a right listing?
2-3
T/F: one must tissue push for an ASLP segmental contact point
false, pull not push
T/F: the doctor should have a 30 degree pivot during inferior knee chest atlas listings
true
T/F: all inferior knee chest atlas listings have tissue pulls
true
What are the lines of drive for an AIRA in knee chest? What side of patient do you stand on?
-L->M
-A->P
-slight I->S
-stand on right side of pt
What are the lines of drive for an AIL in knee chest? What side of patient do you stand on?
-slight I->S
-L->M
-slight A->P
-stand on left side of pt
T/F: right inferior torque is clockwise
false, left is, not right
What are the lines of drive for an AIRP in knee chest? What side of patient do you stand on?
-L->M
-slight I->S
-P->A

Where is the episternal notch point for an AIRA in knee chest?
patient’s chin
Where is the episternal notch point for an AIR in knee chest?
anterior/superior portion of the neck
Where is the episternal notch point for an AIRP in knee chest?
middle of posterior neck
Mastoids should be _______ the head piece for atlas listings
A) hanging off of
B) at the edge of
C) all the way on
B) at the edge of
T/F: the EOP should line up with the VP of the patient
true
What are the lines of drive for an AIRA in side posture?
-L->M

down, forward, C, SCM, mandible
For a BPSR side posture set up, the doctor needs to have __________ pivot
a 45 degree
What is the episternal notch point for an ASR in side posture?
