Cranial Lab 1/8

Question 1

What are the tenets of cranial motion

Answer 1

• fluctuation CSF and potency of tide
• mobility of intracranial and intraspinal membranes, and the function of the reciprocal tension membrane
• inherent motility of CNS
• articular mobility of cranial bones
• involuntary mobility of sacrum between ilia

Question 2

What axis does SBS torsion occur around

Answer 2

anterosuperior-posteroinferior axis (AP)

Question 3

the axis of SBS torsion goes through what bones

Answer 3

nasion through center SBS to opisthion

Question 4

how do we name SBS torsion

Answer 4

side of superior greater wing of sphenoid

Question 5

motion in SBS torsion

Answer 5

sphenoid rotates in one direction and occiput rotates opposite

Question 6

in sidebending rotation what axis does sidebending occur around

Answer 6

parallel vertical axes

one in sphenoid and one in foramen magnum

Question 7

in sidebending rotation what axis does rotation occur around

Answer 7

AP axis in torsion

but now both rotate SAME way

Question 8

how do we name SB/Rot

Answer 8

side of convexity of SBS

SBS moves to R in R sidebending rotation

Question 9

how are vertical strains named

Answer 9

position of basi-sphenoid

Question 10

movements of superior vertical strain

Answer 10

sphenoid flexion

occiput extension

Question 11

movements of inferior vertical strain

Answer 11

sphenoid extension

occiput flexion

Question 12

naming lateral strains

Answer 12

name by position that basi spenoid moves

Question 13

axes in lateral strains

Answer 13

sphenoid and occiput rotate about parallel vertical axes same direction

Question 14

if both sphenoid and occiput rotate clockwise

Answer 14

L lateral strain

Question 15

if both sphenoid and occiput rotate counterclockwise

Answer 15

R lateral strain

Question 16

SBS compression

Answer 16

basi sphenoid and basi occiput approximate to degree that motion in moderately impaired, seriously lacking or almost completely lost

Question 17

where do you rest skull for venous sinus technique ( release occiptal sinus and confluence of sinuses)

Answer 17

rest the head at external occipital protuberance on fingertips of middle fingers

Question 18

when is the venous sinus technique complete for occipital sinus and confluence of sinuses

Answer 18

when perceive melting or softening of bone then move fingers a fingerbreadth down midline occiput

Question 19

jugular sinus technique

Answer 19

decompress occiput from atlas
fingertips along condylar aspect of occiput
weight of head is enough force
hold until feel melting

Question 20

transverse sinus release

Answer 20

resting occipital ridge on fingertips and hold until perceive melthing

Question 21

straight sinus technique

Answer 21

release by placing younr fingertips on occipital ridge and crossing thumbs over each other
rest thumbs on sagittal suture
hold until you perceive meltin

Question 22

sagittal sinus release

Answer 22

thumbs at external occipital protuberance
release superior sagittal sinu with pressure with thumbs on either side of sinue inch above external occipital protuberance
when soften move and inch up and continue until reach bregma
