I just farted while making this flashcard in the library. For posterity's sake the date is 2/4/11 at 12:04 am. I think i need a life. Enjoy the flashcards!

Term
When the posterior aspect of the ethmoid rises, does the SBS rise or descend?
Definition
descends
Term
When the anterior aspect of the ethmoid descends, does the SBS rise or descends?
Definition
descends
Term
When the posterior aspect of the ethmoid descends, does the SBS rise or descend?
Definition
rises
Term
This type of strain is defined as a physiologic adaptation to an upward or downward trauma to one of the four quadrants of the skull.
Definition
Torsion
Term
Torsion Strain occur about which axis?
Definition
an AP axis
Term
How is a torsion named?
Definition
after the position of the greater wing of the sphenoid.
Term
In a torsion strain the occiput and the sphenoid move in the same or opposite direction?
Definition
opposite
Term
While in the vault hold, you feel as if your hands rotate in opposite directions. You diagnose what type of strain?
Definition
torsion
Term
The patient gets whacked on the right side of the occiput. While in the vault hold, you notice that you feel as if you right pinky moves more inferiorly than the left. You diagnose a what?
Definition
Right torsion
Term
The patient gets whacked on the right side of the occiput. While in the vault hold, you notice that you feel as if you right pinky moves more superiorly than the left. You diagnose a what?
Definition
left torsion
Term
The temporals move with the occiput. If the Occiput is inferior, what relative position are the temporals?
Definition
external rotation (flexion)
Term
The temporals move with the occiput. If the Occiput is superior, what relative position are the temporals?
Definition
internal rotation (exhalation)
Term
The patient gets whacked on the right side of the occiput. While in the vault hold, you notice that you feel as if you right pinky moves more superiorly than the left. What relative position are the right and left temporal bones in, respectively?
Definition
internal rotation on the right, external on the left.

(the occiput is superior on the right, therefor internal rotation.

The occiput is inferior on the left, therefore external rotation.
Term
The patient gets whacked on the right side of the occiput. While in the vault hold, you notice that you feel as if you right pinky moves more inferiorly than the left.

What relative position are right and left temporal bones, respectively?
Definition
external rotation (R Temporal)
internal rotation (L Temporal)
Term
You have a right SBS torsion. What relative position is the left temporal bone?
Definition
external rotation
Term
You have a left SBS torsion, what relative position is the left temporal bone?
Definition
external rotation
Term
This strain occurs in response to a traumatic force precisely at the level of the SBS.
Definition
Sidebending rotation.
Term
If you get punched in the right side of the head at the level of the SBS, the convexity of deformation will occur on the same side or opposite side?
Definition
opposite (convex, not conCAVE)
Term
The sidebending component of a sidebending rotation strain is due to which axis?
Definition
the two vertical ones.
Term
Where are the vertical axes in a sidebending rotation strain?
Definition
One directly though the foramen magnum, the other through the body of the spenoid. Oh, and they're parallel.
Term
Where is the rotation axis located in a sidebending rotation strain?
Definition
AP through nasion and opisthion.
Term
In a sidebending rotation strain, the oxiput and the sfeenoyd move in the same or opposite directions about their vertical axis?
Definition
opposite
Term
In a sidebending rotation strain, the temporal bone of the convex side becomes externally or internally rotated?
Definition
externally.
Term
Patient gets thumped at the level of the SBS on the right. The relative position of the left temporal is? how about the right temporal?
Definition
the left is externally rotated. the right is internally rotated.
Term
This type of strain is a result of a blow on the top of the head posterior to the SBS but anterior to the occipital axis.
Definition
superior Vertical strain.
Term
This type of strain is a result of a blow on the top of the head anterior to the SBS but posterior to the sphenoid axis.
Definition
inferior vertical strain
Term
This type of strain is a result of an uppercut to the jaw, anterior to the SBS but posterior to the sphenoid axis.
Definition
superior vertical strain
Term
This type of strain occurs when you land REALLY hard on your heels, which translate the force through the occipital condyles. What strain pattern with this cause?
Definition
inferior vertical strain
Term
In a superior vertical strain, which way will the temporal bones rotate?
Definition
Internally
Term
In an inferior vertical strain, which way are the temporal bones rotated?
Definition
externally
Term
In a superior vertical strain, what are the relative positions of the sphenoid, occiput and temporal bones?
Definition
flexion, extension, internal rotation
Term
This type of strain is characterized by rotation of the sphenoid and occiput in the sambe direction about a parallel vertical axis.
Definition
Lateral Strain
Term
In a right lateral strain, the greater wings of the sphenoid move in what direction?
Definition
left.
Term
in a right lateral strain, the base of the sphenoid moves in what direction?
Definition
to the right (hence the name right lateral)
Term
In a right lateral strain, the part of the occiput anterior to the foramen magnum moves in what direction?
Definition
leftward
Term
In a right lateral strain, the inion will move to the right or to the left?
Definition
to the right! It's posterrior to the axis through the foramen magnum.
Term
You diagnose a left lateral strain. From which direction was the insulting force?
Definition
Two possibilities: at the level of the SBS from the right, anterior to the SBS but posterior to the sphenoidal axis

OR

At the level of the SBS posterior to the SBS but anterior to the foramen magnum.
