QuestionAnswer
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.
