2.Greater wings.
3.Lesser wings.
4.Pterygoid processes.
🗑
|
||||
| The sphenoid articulates with what bones? | show 🗑
|
||||
| show | SBS rises superiorly, Spenoid and occiput rotate in opposite directions about 2 parallel transverse axes.
**Both cause inferior movements and widening. (wrists move apart and head feels fatter)
🗑
|
||||
| show | SBS moves inferiorly. The sphenoid and occiput rotate in opposite directions about 2 parallel transverse axes.
**Both cause superior movements and narrowing.(wrists move closer together)
🗑

| 4 PHYSIOLOGIC strain patterns (normal patterns) | show 🗑
|
||||
| 3 NON-physiologic strain patterns (abnormal patterns) | show 🗑

|
||||
| show | EXTENSION SD
🗑
|
||||
| Physiologic strain pattern: SBS torsion (R&L) | show 🗑
|
||||
| show | Sphenoid and occiput rotate in SAME direction about the AP axis, but they sidebend in OPPOSITE directions about the vertical axis.
**Rotation and name is towards convexity. (The side that gets fatter)
🗑
|
||||
| show | L SBS Sidebending rotation.
**R side will almost feel flat and motionless while the L side bulges.
🗑
|
||||
| show | Sphenoid and occiput rotate in same direction around transverse axes due to shearing force. This causes sphenoid to shift either superior or inferior to occiput.
**named for position of sphenoid base to the occiput base (greater wings will be opposite)
🗑
|
||||
| show | Base of sphenoid shifts up in relation to basiocciput.
**Greater wings go down, index fingers will go down towards patients feet with vault hold.
