Cranial Lab 1/8 Flashcards
What are the tenets of cranial motion
- 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
What axis does SBS torsion occur around
anterosuperior-posteroinferior axis (AP)
the axis of SBS torsion goes through what bones
nasion through center SBS to opisthion
how do we name SBS torsion
side of superior greater wing of sphenoid
motion in SBS torsion
sphenoid rotates in one direction and occiput rotates opposite
in sidebending rotation what axis does sidebending occur around
parallel vertical axes
one in sphenoid and one in foramen magnum
in sidebending rotation what axis does rotation occur around
AP axis in torsion
but now both rotate SAME way
how do we name SB/Rot
side of convexity of SBS
SBS moves to R in R sidebending rotation
how are vertical strains named
position of basi-sphenoid
movements of superior vertical strain
sphenoid flexion
occiput extension
movements of inferior vertical strain
sphenoid extension
occiput flexion
naming lateral strains
name by position that basi spenoid moves
axes in lateral strains
sphenoid and occiput rotate about parallel vertical axes same direction
if both sphenoid and occiput rotate clockwise
L lateral strain
if both sphenoid and occiput rotate counterclockwise
R lateral strain
SBS compression
basi sphenoid and basi occiput approximate to degree that motion in moderately impaired, seriously lacking or almost completely lost
where do you rest skull for venous sinus technique ( release occiptal sinus and confluence of sinuses)
rest the head at external occipital protuberance on fingertips of middle fingers
when is the venous sinus technique complete for occipital sinus and confluence of sinuses
when perceive melting or softening of bone then move fingers a fingerbreadth down midline occiput
jugular sinus technique
decompress occiput from atlas
fingertips along condylar aspect of occiput
weight of head is enough force
hold until feel melting
transverse sinus release
resting occipital ridge on fingertips and hold until perceive melthing
straight sinus technique
release by placing younr fingertips on occipital ridge and crossing thumbs over each other
rest thumbs on sagittal suture
hold until you perceive meltin
sagittal sinus release
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
