There are forces that govern our life on planet earth, and structures within our bodies that meet and distribute those forces. The primary field is one we take for granted until we are very far off the ground: gravity.
Our bodies are constructed to funnel this immutable force into the earth. Our bones hold us up within this field, and their alignment or misalignment affects the shape and quality of the soft tissues that attach to them. The contraction of our muscles pulls blood, so the circulation of our blood is also affected.
Our funnel we make in response to gravity's load over the duration of our lifetime is what shapes our bones, and every cell within our body. We never escape its pull as long as we are alive; quite literally the shape you make in gravity is an autobiography of the life you have lived, and “a living story you are continuously writing” (Katy Bowman).
Far From Equilibrium dynamics is the underlying physics to the organization of our body's form in gravity. The body is bioelectric, and respond to mechanical input. At the cellular level, the process by which our physical self adapts to its own shape in the physical world and field of gravity is called mechanotransduction.
The process by which cells adjust their structure and function according to environmental stimulus created by their physical environment. This translation of mechanical signals into biochemical ones, is responsible for a number of senses and physiological processes in the body, including proprioception, touch, balance, and hearing.
When we move, we are not only rearranging our spine and peripheral parts, but we are also organizing the very smallest structures that our bodies are comprised of, our cells. Our entire body is made up of cells. The cells create a matrix, and in order of organizational complexity then create tissues, organs, organ systems and finally the whole body.
Our cells have their own cytoskeleton that holds them up against the Earth's gravitational force. At various times, other forces load them as well, such as the push/pull force of objects in our physical world. There are three forms of mechanical input to our bodies: external pressures, frictions and tractioning.
