Midterm Extra Info Flashcards
(99 cards)
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
