What are the paired bones in the cranial vault?
Frontals Parietals Temporals - Squamous Occiput - Greater wings of the sphenoid
What axis do the midline bones move around, and thus, what are their movement options?
Transverse axis
= Flexion or Extension
Paired bones have many axes, what are their movement options?
External or Internal Rotation
With Cranial Flexion, which direction do paired bones move?
External Rotation
If the paired bones are externally rotating, what direction is the cranium going?
Flexion
The Ethmoid moves in the same direction as which bone?
Occiput

With the Vault contact, what bones are the palms on?
Parietal bones
Describe the Frontal Occipital Contact?
One hand cradling head via occiput
Other hand has one thumb on the greater wing of the sphenoid and the index/middle finger on the other greater wing of the sphenoid
Describe the Becker contact?
