| Question | Answer |
| 5 components of PRM | 1.motility of brain and spinal cord. 2.fluctuation of CSF. 3.Mobility of intracranial and intraspinal membranes. 4.Mobility of cranial bones. 5.Involuntary mobility of the sacrum b/w the ilium. |
| What all is included in the cranial base? | formed by cartilaginous bone instead of membranous bone. Consists of: 1.Sphenoid. 2.Occiput. |
| Does a synchondrosis contain synovium? | NO. union of 2 bones by fibrocartilage or hyaline cartilage. |
| What is the sphenobasilar synchondrosis? | fibrocartilage junction b/w the basisphenoid and the basiocciput. |
| Cranial base Strains are named based on what cranial structure's motion? | SBS |
| 4 parts to the sphenoid | 1.Central body. 2.Greater wings. 3.Lesser wings. 4.Pterygoid processes. |
| The sphenoid articulates with what bones? | 1.Frontal. 2.Parietal. 3.Temporal. 4.Occiput. 5.ethmoid. 6.palatines. 7.vomer. 8.Zygomatic bone. |
| Motion of the SBS during flexion | 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) |
| Motion of the SBS during extension | 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) | 1.Flexion. 2.Extension. 3.Torsion (R & L). 4.Sidebending rotations (R & L). **NOT related to trauma |
| 3 NON-physiologic strain patterns (abnormal patterns) | 1.Vertical strains (Inferior & superior). 2.Lateral strains (R&L). 3.SBS compression (no movement at all: 0/5). **Usually DO to TRAUMA |
| Physiologic strain pattern: Flexion SD | Extreme or exaggerated flexion with DECREASED extension of SBS. **Football or Ernie head. |
| Physiologic strain pattern: Extension SD | Extreme or exaggerated extension with DECREASED flexion of the SBS. **Skinny or Bert head. |
| What type of physiological strain pattern would cause sinus drainage and asthma problems? | EXTENSION SD |
| Physiologic strain pattern: SBS torsion (R&L) | Sphenoid and occiput rotate opposite directions about the AP axis. Named by which greater wing of sphenoid goes superior. **if R index finger rises, R torsion. If L index finger rises, L torsion |
| Physiologic strain pattern: SBS Sidebending Rotation | 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) |
| What type of strain: L hand gets wider and drops lower than the R. R gets more narrow | L SBS Sidebending rotation. **R side will almost feel flat and motionless while the L side bulges. |
| Non-Physiologic strain pattern: Vertical strain | 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) |
| Non-Physiologic strain pattern: Superior vertical strain | Base of sphenoid shifts up in relation to basiocciput. **Greater wings go down, index fingers will go down towards patients feet with vault hold. |
| Non-Physiologic strain pattern: Inferior vertical strain | The base of the sphenoid moves inferiorly to the basiocciput. **Greater wings will go upwards and Index fingers will come back towards you with vault hold. |
| Getting a helmet to helmet hit to the top of the head would cause what type of vertical strain? | Inferior |
| Getting an uppercut to the chin could cause which type of vertical strain? | Superior |
| Non-Physiologic strain pattern: Lateral strains | Sphenoid and occiput rotate in the same direction around 2 parallel vertical axis due to shearing force just ant or posterior to SBS. **named for position of basisphenoid to basiocciput. |
| Non-Physiologic strain pattern: L lateral strain | Sphenoid base is sheared L in relation to basiocciput. **Both index fingers will move to the R, both PINKY fingers to the L |
| Non-Physiologic strain pattern: R lateral strain | Sphenoid base is sheared to the R in relation to the basiocciput. **Both index fingers will move to the L, both PINKY fingers to the R |
| Non-Physiologic strain pattern: SBS compression | Sphenoid and Occiput have been forced together. little or no motion. **Graded 0/5 |
| causes of SBS compression | 1.Trauma. 2.Fever. 3.metabolic problems. |
| What can be responsible for suckling dysfunctions in newborns? | 1.Occipital condylar compression (XII). 2.Dysfunctions of IX & X at jugular foramen. |
