Overview Number of Axises = 3 Type of Axis Sidebending – 2 parallel vertical axises 1 through foramen magnum (occipital bone) 1 through body of sphenoid Sphenoid and occiput rotate in opposite directions about vertical axes (clockwise, counterclockwise) Rotation – 1 Anteroposterior (AP) axis AP axis through the sphenoid and […]

Overview Number of Axes = 1 Type of Axes = 1 Anteroposterior (AP) axis through the sphenoid and occiput The sphenoid and occiput rotate in opposite direction about this single AP axis Naming The naming of cranial torsions is based on the side with the higher wing of the sphenoid […]
Overview 2 parallel transverse axes (red lines in images below) 1 axes through the sphenoid bone (purple bone below) 1 axes through the occipital bone (white bone below) Naming The naming of cranial flexion/extension motion is based on flexion or extension of the midline bones of the skull (sphenoid, occipital, […]
Overview Physiological strain patterns are “normal” types of cranial motion The 3 types of physiologic motions are: Flexion/Extension Torsions Sidebending/Rotation In a lab setting, you will be asked to demonstrate these motions using your hands On a written or oral exam, you may be asked to indicate the number of […]
