Osteopathy differentiates between bodily structures (e.g. bones, muscles, organs, nerves, bodily fluids) and bodily functions (circulation, digestion, etc).
Structure and function mutually influence each other and must therefore be regarded together. In this way, a random change in function (e.g. through incorrect load/strain) can change a structure (e.g. calcification); whilst a change in bodily structures (e.g. caused by an accident) can impair function.
„The function creates the structure – the structure governs the function.“ (Andrew T. Still)
