Cranial Strains and Movement Patterns Flashcards
midline bones
occiput sphenoid mandible vomer ethmoid frontal
Paired bones
frontal parietal squamous temporals squamous occiput inferior nasal concha lacrimal maxilla nasal palatine zygoma frontal
Midline bones
flexion/extension
usually rotate about a transverse axis in a anterior/posterior direction
paired bones
internal/external rotation
usually move about AP axis in a lateral motion
Ethmoid parts
horizontal - cribriform plate
perpendicular plate
lateral masses (2)
Ethmoid flexion
rotates around a transverse axis
crista galli swings superiorly and posteriorly
lateral masses externally rotate(expand inferiorly)
Ethmoid extension
rotates around a transverse axis
crista galli swings inferiorly and anteriorly
lateral masses internally rotate(compress inferiorly)
5 articulations of the Vomer
nasal septum ethmoid sphenoid palatines maxillae
Vomer flexion
rotates around a transverse axis
wide flat palate
posterior part depresses the palatine, flattening the roof of the mouth
anterior part ascends to allow premaxillae to externally rotate
Vault Contact
Index fingers rest of the greater sphenoid wing, just posterior to the frontozygomatic suture
Middle fingers anterior to the ear on temporal
ring fingers rest on the mastoid process
pinky fingers rest on the occiput
palms may rest upon the parietals
thumbs may contact the frontal bone
Lateral Strain Axis
Two vertical axis
Lateral Strain Names
for the direction of the base of the sphenoid
Lateral Strain Motion
motion happens in the same direction
Lateral Strain Palpation
1st fingers move in opposite direction from pinky fingers
side of strain moves anteriorly
Vertical Strain Axis
two transverse axis
