The Sphenoid "Keystone" Bone

The human head has been likened to a bowling ball in weight and approximate size. The term "bowling ball syndrome" was given for problems arising from this ever present, downward pushing weight onto an improperly aligned skeletal structure.

The bones of the skull apparently are not immobile as was previously believed.  The "butterfly" shaped sphenoid cranial bone is the equivalent to the "keystone" top stone of a stone arch, but the arch of cranial bones is upside down, with the weight of the head resting upon the sphenoid. If the keystone shifts, the whole arch will also experience a change in position.

So it is with the sphenoid and the center of gravity of the head, which affects the position of rest of the body structure.
Injury or other reasons can cause the sphenoid to shift out of place, causing a disturbance that can eventually manifest in the entire body structure. It seems the body compensates for this misalignment, and the effects can range from increased ear infections from the pressure on the ear canal, all the way to a rotated pelvis. In the particular case shown in the following video, the woman's ears, shoulders, and hips are out of level, presumably due to a dislocation of the sphenoid. Dr. Jerry Tennant of the Tennant Institue of Dallas, Texas displays a revolutionary, non-invasive correction of the sphenoid by pulsing tiny amounts of electricity into the neck region of the trapezius muscles, stimulating them to pull the sphenoid back into alignment.

Quite interesting how this switched back on the cranio-sacral pump which replenishes the nervous system by circulating the cerebral spinal fluid, causing those back and forth motions when the eyes are closed in standing position.

Whoever discovered this procedure deserves some kind of prestigious award!
