Everything in context
Osteopathy treats the body on all parts.
The parietal system: Bones and muscles;
The visceral system: The organs;
The craniosacral system: The skull with the sacrum.
If there is a problem in one of these systems, then it will involve the two other systems.
This can be done via the mechanical, or by decreased blood flow, or through the nervous system,
and very often a combination of these.
The osteopath will interrelate these systems.
Again, this is called Holism.
