physiologic cranial SBS patterns
torsions
sidebending rotation
torisons are named for?
they have a _ axis and they rotate in what direction
the greater wing of the sphenoid that moves superiorly
sagital axis (a-p)
rotate in opposite directions
sidebending rotation is named for ?
axes?
rotation around axes?
base of the sphenoid
1 sagital axis
2 vertical axis
same direction in sagital axis
opposite direction in vertical axes
what are the non physiologic cranial SBS patterns
vertical strain, lateral strain, SBS compression
vertical strain is named for
(greater stresses invloved in the side of strain)
axes?
rotation around the axes?
the base of the sphenoid
two transverse axes
motions are in the same direction around the axes (superior strain- anteriorly, inferior strain- posteriorly)
lateral strain is named for?
axes?
rotation around the axis?
base of the sphenoid
2 vertical axes
same direction around the axes
SBS compression is a _ axis compression
sagital
what causes SBS compression
trauma/sustained pressure
SBS compression is associated with?
depression and anxiety
SBS flexion and the sacrum
pulls dural sleeve of the cord and pulls the sarcum postrioly into counternutation
the dural sleeve of the spinal cord attaches where
at the foramen magnum and s2
SBS extension causes sacral _
nutation (moves anteriorly)
the sacrum moves in the same way as the _ because of the dural pull as the foramen magnum rises in flexion
occiput
