10 - 14 cycles per minute
|
|
|
Decreases rate and quality of CRI
|
1. Stress (emotional, physical)

|
|
|
Meninges 3 membrane layers
|
1. Dura mater (outer most membrane)
2. Arachnoid mater 3. Pia mater |
|
|
What meninges layer forms the falx cerebri and tentorium cerebelli?
|
Dura mater
|
|
|
What are the midline bones of the cranium?
|
sphenoid, occiput, ethmoid, and vomer
|
|
|
What is another name for sacral extension?
|
counternutation
|
|
|
Flexion at the SBS causes the dura to be pulled in which direction?
The sacral base moves in what direction? |
Dura moves cephalad
Sacral base counternutates |
|
|
What does cranial flexion do to anteriorposterior diameter of the head?
|
Decreases the AP diameter
|
|
|
During Cranial extension, the paired bones of the cranium moves which way? External rotation or internal rotation?
|
internal rotation
|
|
|
During cranial extension, which way does the dura go? Cephalad or Caudad
|
Caudad
|
|
|
Which way does the sacral base move during cranial extension?
|
Nutates: sacral flexion
|
|
|
What happens to the head's AP diameter during cranial extension?
|
Increases AP diameter
|
|
|
Describe how cranial torsion is named to get Right Torsion or Left Torsion
|
named for the greater wing of the sphenoid that is more superior.
(i.e. left torsion has the left greater wing superior to the right. occiput and posterior cranium rotate in the opposite direction |
|
|
Describe how cranial sidebend/rotation strain is named to be SBR.l or SBRr
|
Naming of left or right is based on which way the sphenobasilar synchondrosis is deviated. When deviated right, will see wider opening of SBS on the right. Right side of sphenoid will become inferior. Occiput will rotate in the same direction (right in this example)
|
|
|
Which cranial strains are physiologic?
These do not interfere with flexion or extension of craniosacral motion |
1.,2. Flexion and Extension but only if it does not interfere with flexion or extension motion
3.,4.Right and Left Torsion 5.,6. SBR left and SBR right |
|
|
How is vertical strain of the SBS named?
|
Superior vertical strain means the sphenoid deviates cephalad compared to the occiput.
Inferior vertical strain means the sphenoid is caudad compared to the occiput. |
|
|
Which strain makes the cranium feel like a parallelogram?
|
Lateral strain
|
|
|
How might one get a cranial lateral strain?
|
Get hit on the side of the head in the front.
|
|
|
How is lateral strain named?
|
sphenoid will deviate left or right in comparison to the occiput.
|
|
|
Decribe the location of the sphenoid and occiput in a compression strain
|
sphenoid and occiput are pushed together.
|
|
|
Mechanism of getting a compression strain
|
hit in the back of the head.
|
|
