Midterm Extra Info Flashcards
CRI rate
10-14 BPM
CRI direction
linear and symmetric
CRI characteristics (RRADS)
Rate, Rhythm, Amplitude, Direction, Strength
Function of dural folds (falx cerebri/cerebelli and tentorium cerebelli) in cranial movement
act as reciprocal tension membranes, springing the cranial bones
storing energy in flexion (stretch) and releasing in extension (rebound)
SBS flexion/inhalation
Sphenoid rotates anteriorly,
Occiput rotates posteriorly
head gets shorter and wider
SBS extension/exhalation
Sphenoid rotates posteriorly,
Occiput rotates anteriorly
head gets longer and narrower
Sacral motion in SBS flexion
counternutation : dural pull, sacral base moves posterior
Sacral motion in SBS extension
nutation : dural release, sacral base moves anterior
*moves towards the nuts
CNs that travel thru the optic canal (1)
Optic
CNs that travel thru the superior orbital fisure (4)
Oculomotor
Trochlear
V1 (opthalamic)
Abducens
CNs that travel thru the foramen rotundum (1)
V2 (maxillary)
CNs that travel thru the foramen ovale (1)
V3 (mandibular)
CNs that travel thru the internal acoustic meatus (2)
Facial
Vestibulocochlear
CNs that travel thru the jugular foramen (3)
Glossopharyngeal
Vagus
Accessory
SBS joint type
synchondrosis of hyaline cartilage
Paired bones in cranial motion (3)
Frontal, Parietals, Temporals
flexion and extension
Paired cranial bone movement in flexion
EXternal rotation in flEXion
flexternal
Paired cranial bone movement in extension
internal rotation
Ethmoid movement in cranial motion
rotates same direction as occiput (vowels move together)
- moves like a gear against the sphenoid
- sphenoid rotates forward in flexion, so ethmoid/occiput rotate backward
Vomer movement in cranial motion
rotates same direction as sphenoid (consonants move together)
*sphenoid rotates forward in flexion, so vomer rotates forward
Doc who invented cranial omm
William Garner Sutherland
Rotation axis of midline bones (occiuput, sphenoid, ethmoid, vomer)
transverse axis (F/E)
Rotation axis of paired bones
saggital axis (IR/ER)
Cranial vault contact
Thumbs: Frontal Index: Greater wing sphenoid Middle: Anterior to ear Ring: Mastoid process Pinky: Occiput Palms: Parietals
Frontal occipital contact
Top hand: thumb and index finger on opposite greater sphenoid wings
Bottom hand cradles occiput
Becker contact
thumbs on greater sphenoid wings
Left Torsion
Saggital axis (opposite)
Air hands: rotate opposite directions w/
Lt index going up, Rt index going down
Right Torsion
Saggital axis (opposite directions)
Air hands: rotate opposite directions w/
Rt index going up, Lt index going down
Right Sidebending Rotation
Saggital axis (same), 2x vertical axes (opposite)
Air hands: spread and scrunch
Rt hand gets wider, Lt hand gets narrower
*named based on wide side
Left Sidebending Rotation
Saggital axis (same), 2x vertical axes (opposite)
Air hands: spread and scrunch
Lt hand gets wider, Rt hand gets narrower
*named based on wide side
Superior Vertical Strain
Parallel transverse axes (same)
Air hands: rotate same direction
Lt and Rt hand rotate forward
*named for base of sphenoid movement
Inferior Vertical Strain
Parallel transverse axes (same)
Air hands: rotate same direction
Lt and Rt hand rotate backward
*named for base of sphenoid movement
Left Lateral Strain
Parallel vertical axes (same)
Air hands: parallelogram
Pinkies shift Lt, Index fingers shift Rt
Right Lateral Strain
Parallel vertical axes (same)
Air hands: parallelogram
Pinkies shift Rt, Index fingers shift Lt
Strain pattern caused by trauma at the temporal bone (DIRECTLY AT THE LEVEL OF THE SBS)
Sidebending rotation strain
Strain pattern caused by trauma at the pterion or asterion (anterior or posterior to the SBS)
Lateral strain
Strain pattern caused by downward force on top of the frontal bone, or upward force at the occiput
Inferior strain
*both would cause the base of the sphenoid to move (relatively) inferiorly
Strain pattern caused by upward force on the mandible, or downward force at the saggital suture (parietal bones)
Superior strain
*both would cause the base of the sphenoid to move (relatively) superiorly
Strain pattern caused by rotational force anterior or posterior to the SBS
Torsion strain
