How many axes are involved in cranial flexion and extension?

Cranial flexion and extension occur around two transverse axes, which are critical for understanding cranial osteopathic mechanics. These axes allow for the movement of the cranial bones as they flex and extend, facilitating the overall dynamic motion of the cranium in relation to the spinal column.

When the head is in the flexed position, the occipital bone moves anteriorly and the temporal bones rise, while during extension, the occipital moves posteriorly, bringing the bones back to a neutral position or extending them further. This movement is an essential aspect of cranial mechanics and is crucial for practitioners to understand in order to assess and treat cranial dysfunctions appropriately.

Recognizing that there are two transverse axes involved is fundamental not only in osteopathic practice but also in understanding the interconnectedness of cranial bones and their mobility in relation to one another during cranial mechanics.
