CPA1 - Cranial Movements Flashcards
Which way do the sphenoid and occiput move during cranial flexion?
Sphenoid = greater wings move anterior/inferior Occiput = membranous portion moves posterior/inferior
Which ways do the sphenoid and occiput move during cranial extension?
Sphenoid = greater wings move posterior/superior Occiput = membranous portion moves anterior superior
How would you describe a flexion dysfunction of the SBS?
The sphenoid and occiput move further during flexion than extension
How would you describe an extension dysfunction of the SBS?
The sphenoid and occiput move further during extension than flexion
How does the sacrum move in cranial flexion and extension?
Cranial flexion = counternutation
Cranial extension = nutation
During cranial flexion, how does the SBS move?
Superiorly
During cranial extension, how does the SBS move?
Inferiorly
For SBS lateral strain patterns, describe the axes of movement, the position for which the dysfunction is named, and how the hands of the doc will move.
Axes = vertical Name = basisphenoid Hands = slide over each other (parallelogram)
For SBS vertical strain patterns, describe the axes of movement, the position for which the dysfunction is named, and how the hands of the doc will move.
Axes = transverse Name = basisphenoid Hands = thumbs move toward/away from doc in same direction
For SBS torsion patterns, describe the axes of movement, the position for which the dysfunction is named, and how the hands of the doc will move.
Axes = AP axis Name = most cephalad greater wing Hands = one thumb towards doc, other thumb away from doc
For SBS side-bending/rotation patterns, describe the axes of movement, the position for which the dysfunction is named, and how the hands of the doc will move.
Axes = side-bending in vertical through body and foramen magnum Name = side of convexity Hands = one hand down and out, other hand up and in
During cranial flexion, how do the parietal bones move and along which axis?
External rotation about AP axis (inf border moves lat)
During cranial extension, how do the parietal bones move and along which axis?
Internal rotation about AP axis (inf border moves med)
During cranial flexion, how do the temporal bones move and along which axis?
External rotation about oblique axis (sup border moves ant lat)
During cranial extension, how do the temporal bones move and along which axis?
Internal rotation about the oblique axis (sup border moves post med)
