Cranial

Question 1

list midline bones

Answer 1

SOS EV
sphenoid, occiput, sacrum, ethmoid, vomer
FLEXION and EXTENSION

Question 2

paired bones

Answer 2

do ER and IR

lateral mass of ethmoid, everything else

Question 3

SBS during flexion

Answer 3

Flexion = ER= increased transverse diameter (Ernie)
occurs during inhalation
occurs around 2 transverse axes at formamen magnum and spenoid

Question 4

SBS durign extension

Answer 4

Extension = IR= increase AP diameter (Burt)= occurs during exhalation

Question 5

Things that increase the Primary Respiratory Mechanism

Answer 5

exercise
fevers
OMT

Question 6

Things that decrease the PRM

Answer 6

stress, fatigue, infection, depression, poision

Question 7

RTM

Answer 7

reciprocal tension membrane is made up of the falx, tentorium, dural reflections

Question 8

Cranial rhythmic impulse

Answer 8

cycles 10-14/min

Question 9

Sacral motion

Answer 9

occurs at 2nd segment, posterior to canal (respiratory axis)

Question 10

Sacral motion during cranial flexion

Answer 10

counternutation
sacral base moves posterior
Apex moves anterior
=extension

Question 11

Sacral motion during cranial extension

Answer 11

nutation
sacral base moves anterior
apex moves posterior
= flexion

Question 12

Torsion

Answer 12

sphenoid and occiput move in opposite directions
named for superior wing of sphenoid
on side of torsion: index finger moves towards, pinkie moves away

Question 13

sidebending rotation

Answer 13

spenoid and occiput rotate in opposite directions aroudn parallel vertical axes and rotate in the same direction round AP axis

named for the side of convexity (inferior side)
fingers on the strain side spread and move inferior

Question 14

Superior/Inferior (vertical) strain

Answer 14

the sphenoid and occiput move in opposite directions on two parallel transverse axes creating a shearing force on the SBS
named for the position of the basal sphenoid (superior)
inferior- landing on buttocks)
superior- hitting top of occiput on cabinet

Question 15

Lateral Strain

Answer 15

sphenpoid and occiput rotate in same direction around a parallel vertical axis, causing shearing of the SBS
named for how the basal sphenoid moves

hands form a prallelogram with index fingers moving one way and pinkies moving another way
-got hit in the side of the head

Question 16

extreme flexion

Answer 16

SBS is elevated AP diameter decreases, transerse diameter decreases, cranium prefers flexion and ER, sacrum is extened (CN) with the sacral base posterior

round face, wide orbits, protruding eyes,

Question 17

Extreme extension

Answer 17

SBS is depress, increased AP diameter , decreased Transverse diameter, cranium preferes extension and IR, sacrum is flexed (N) with sacral base anterior
narrow face, narrow orbits, retruded eyes, ears close to head, palate narrow and high

Question 18

SBS compression

Answer 18

occiput and sphenoid are compressed together along the AP axis, fingers of both hands approximate
F/E are limited 
Decreased PRM rate
head feels hard 
-got punched in the nose
