MIdterm Flashcards
What are the five components of PRM
Inherent mobility of brain and SC, fluctuation of CSF, mobility of intracranial and intraspinal membranes, articulatory mobility of cranial bones, involuntary mobility of sacrum btw ilia
What creates cranial motion
Glial cells
What is the layer palpation used for cranial
Hair, skin, subcutaneous tissue, bone
Can you feel the CRI if a patient holds their breath
Yes
What is the Sutherland fulcrum
Functional name given to straight sinus
What is reciprocal tension membrane aka core link
Meninges and the cord constitute a link btw cranium and the sacrum
What fascia affect the PRM
Pannicular, axial and appendicular, meningeall, visceral
What creates the reciprocal tension membrane
Falx cerebra and cerebellum and tentorium; holds vault and base under constant tension; allows for change in the vault while maintaining constant volume; allows but limits motion
What are the main poles of attachment of the RTM
- anteriorsuperior pole: Crista Galli
- anterior/inferior pole: clinoid process of sphenoid
- lateral pole: mastoid angels of parietals and petrous ridges of temporal bone
- posterior pole: internal occipital protruberance and transverse ridges
What is a suspended automatic shifting fulcrum
Suspended: moves but remains in RTM
Automatic: moves with motion of CRI
Shifting: straight sinus moves up and down
Where is the point of function
Straight sinus - junction of falx and tentoria
What is extension of SBS paired with in terms of breathing
Exhalation; cheekbones prominent; SBS decreased angle
Where does the dura attach that influences sacral motion
Foramen mangnum and posterior body and disc of S2
What is the postural sacral axis
Transverse axis of nutation/counternutation throuh anterior part of S2
What is the pelvic/ileal axis
Functional transverse axis at S3; movement of ilia on sacrum
What axis does movement occur on for the sacrum during PRM
Superior transverse
What contributes to health
Unity, structure/function, and self healing
What are the models of osteopathic treatment
Postural structural, neuro, respiratory circulatory, bioenergy, psychosocial
What does the approach to the patient of osteopaths look like
Structural exam (objective); changing* address the cause and not the effect
What are the midline (unpaired) bones
Sphenoid, occiput, ethmoid, mandible, vomer, frontal
What are the paired bones
- cranial vault: parietal, temporal, squamous temporal, frontal
- facial: inferior nasal concha, lacrimal, maxilla, nasal, palatine, zygoma
What axis do the paired bones usually rotate around
AP axis in the coronal plane
What are the parts of the ethmoid
- horizontal: cribriform plate; includes crista galli
- perpendicular plate
- lateral masses: form orbital plates - medial walls of orbit; forms middle and superior concha
How does the ethmoid move in flexion
Perpendicular plate is rotated by the sphenoid about its transverse axis; crista galli moves superiority and posteriorly
-external rotation: lateral masses expand inferiorly due to pull of external rotation of maxillae
How does the ethmoid move in extension
Crista galli moves inferiorly and anteriorly
-internal rotation
What clinical considerations would you consider for an ethmoid dysfunction
- Sinusitis: lateral masses move into external rotation with widening o ethmoid notch and external rotation of maxillae, opening nasal passage; ER/IR creates pumping acting on ethmoid sinus
- septal deviation
- headache: lymphatic backup -> increased dural tension and vascular effects
What does the vomer articulate with
Sphenoid, ethmoid, septal cartilage, maxillae, palatines
Describe the motion of the vomer in flexion and extension
Flexion: wide flat palate
Extension: narrow, tall palate
*depresses the hard palate with SBS flexion
How do the ethmoid and vomer move during SBS flexion
Ethmoid: same as occiput
Vomer: same as sphenoid
What do the palatines articulate with
Sphenoid, ethmoid, maxilla, vomer, contralateral palatine, inferior concha
How do the palatines move during flexion
Palate flattens; eternally rotates (horizontal plate moves laterally and inferiorly)
What are clinal correlations for dysfunction of palatine
Swallowing/speech difficulties
How do you name a torsion
Superior sphenoid wing
What axis is involved in a torsion
AP (rotate in opp direction)
What axes are involved in lateral strains
2 vertical axes; sphenoid and occiput spin in same direction
How do you name a lateral strain
Direction of the translation of the basisphenoid (ie: left would be sphenoid base to left and occipital base to right)
How do you name sidebending rotation
Flexed side (convex side)
How do you test for SBS compression
Lift lateral angles of frontal bone anteriorly with the thumbs while stabilizing the lateral angles of the occiput posteriorly with the hands in vault hold
What does the parietal bone articulate with
Occiput, frontal, sphenoid temporal, opposite parietal
Which bone is the only one that connects all 4 fontanelles
Parietal
Where is the origin of the temporalis m
Lower temporal ridge
What happens to the Pterion asteroid and squamous sutures during flexion
Move laterally
What happens to the Sagittal suture during flexion
Ones inferiorly
