what 5 things does the primary respiratory mechanism involve?
inherent motility of the CNS, mobility of the intracranial and intraspinal membranes, fluctuation of the CSF, mobility of the cranial bones and involuntary mobility of the sacrum btwn the ilia.
what are the 5 membranes associated with the myofascia/ dura of the cranium?
falx cerebri, tentorium cerebelli, falx cerebelli, diaphragma sellae, and spinal dura
what is the corelink?
the linkage btwn the cranial bones and the sacrum.
what is the dura attached to that you can use to tx headaches?
c2
what is the inferior attachment of the dura?
posterior body of S2
how does venous blood exit the skill?
internal jugular through paired jugular foramina
where does 95% of the venous blood drain into? what foramen? what bones border this foramen?
jugular vein which passes through the jugular formanen which is bordered by the occipital and temporal bones
how many key venous sinuses are w/n the cranium?
16
where does the superior sagittal sinus run? what does it lie within?
from the foramen cecum anteriorly to the confluence of sinuses posteriorly and lying w/n the attached margin of the falx cerebri.
in about 60% of cases, what does the superior sagittal sinus empty into?
confluence of sinuses in the area of the right transverse sinus
where does the inferior sagittal sinus lie? where does it empty into?
posterior portion of the free margin of the falx cerebri and empties into the straight sinus.
what forms the straight sinus? where is it formed?
formed by the joining of the great cerebral vein and the inferior sagittal sinus. Formed at the junction of the falx cerebri and tentorium cerebelli.
where does the occipital sinus run? where does it empty into?
runs from external occipital protuberance down thru the foramen magnum formed w/n the attached falx cerebelli. It empties into the confluence of sinuses
what is the circular sinus made up of? what does it encircle and empty into?
made up of 2 cavernous sinuses just behind the eyes and their communicating branches. It encircles the hypophysis and empties into the superior and inferior petrosal sinuses b/l
where does the basilar plexus lie and what does it join?
lies over the SBJ and joins the circular sinus w/ internal vertebral plexus.
what are the 6 midline venous sinuses?
-superior and inferior sagittal sinus
- straight sinus
-occipital sinus
-circular sinus
-basilar plexus
where do the transverse sinuses run? what do they become?
they run laterally from the confluence of sinuses (at inion) at the internal occipital protuberance. Each sinus becomes a sigmoid sinus in the area of the mastoid portion of the temporal bone--> continues toward the jugular foramen and internal jugular vein.
where do the cavernous sinuses lie? where do they receive venous flow from? what do they contain?
lie on each side of the body of the sphenoid.
venous flow is received from the ophthalmic vein, superficial middle cerebral vein and sphenoparietal sinus.
the sinuses contain the carotid artery, abducent, oculomotor, trochlear, ophthalmic division of the trigeminal nerves.
where do the superior petrosal sinsuses lie? where do they run?
w/n the margin of the tentorium cerebelli and runs along the petrous ridge of the temporal bone from the cavernous sinus to the transverse sinus.
where do the inferior petrosal sinsuses run? what do they connect?
runs in the groove in the suture between the petrous portion of the temporal bone and the occipital bone. it connects the cavernous sinus to the internal jugular vein.
what are the 6 indications for venous sinus technique?
headaches
sinus congestion
reduce compression at the sphenobasilar jxn
reduce compression at many cranial sutures
augment endocrine fxn
improve overall cerebral fxn.
what structure related to endocrine function surrounds the stalk of the pituitary?
diaphragma sella
what nerve innervated the dura?
CN V
what are the 9 relative contraindications for venous sinus technique?
Recent trauma with suspected significant or serious injury to the brain, blood vessels, cranium, or other related structures.
Certain infections such as meningitis or encephalitis.
Elevated intracranial pressure.
Cerebral edema.
Recent shunt surgery or neurosurgery. <3 months
Recent stroke. <3 months
Brain or other intracranial tumor.
Congenital malformations.
Other potential conditions not treatable with OMT
what are the 6 steps of the venous sinus technique tx?
Confluence of sinuses (inion*)
Occipital sinuses (supraocciput)
Occipital condylar decompression
Transverse sinuses (external occipital protuberance)
Straight sinus (bregma and inion)
Sagittal Sinus (sagittal and metopic sutures)
define inion
a point located on the external occipital protuberance at the intersection of the midline with a line drawn tangent to the uppermost convexity of the right and left superior nuchal lines.
where are the two middle fingers located during the confluence of sinuses step?
tip to tip with the pads on the external occipital protuberance (inion)
where are the fingers located during the occipital sinuses step?
finger's width midline on the occipital bone
where are the fingers located during the occipital condylar decompression step?
at the angle of the condyles. Toward the foramen magnum

- take the condyle towards the table and a little lateral
where are the fingers located during the transverse sinuses step?
along the external occipital protuberal transversely. Do not go any further anterior than the mastoid process
the straight sinus forms a straight line from ____ to bregma
inion
where is the origin for the sagittal sinus step? what is the movement of this step?
anterior of lambda. thumbs are crossed and apply a gentle separating force across the sagittal suture. Continue moving the thumbs anterior to go the length of the sagittal suture.
