Weird Bone Stuff Flashcards
What does the ethmoid articulate with?
Frontal, sphenoid, vomer, maxillary, palatine, and nasal
What does the vomer articulate with?
Sphenoid, ethmoid, septal cartilage, maxillae, and palatines
When the SBS is in flexion, what do the ethmoid and vomer move in the same direction as?
Ethmoid moves in the same direction as the occiput
Vomer moves in the same direction as the sphenoid
If your sphenoid is extended, what is your sacrum?
Nutation (flexion for the sacrum)
Where would trauma occur to cause lateral strain?
Temporal bone by the pterion and by the occipitomastoid suture
Where would trauma occur to cause vertical strain?
Superior: mandible and lamboid
Inferior: frontal bone (downward) and occiput (upward)
What trauma would occur to cause torsional strain?
Mandible (upward)
Occipitomastoid junction either upward or downward
What trauma would occur to cause sidebending rotation?
Right in the ear
What is the motion of the apex of the sacrum in SBS flexion?
Anterior
What axis does motion of the sacrum occur
Superior transverse axis
The asterion is made up of which bones?
Parietal, temporal, and occiput
What strain pattern coincides with TBI and decreased CRI?
SBS compression
