John, the contraction of the diaphragm (it's a muscle - contraction is the only thing it can do) causes inhalation by increasing the volume of upper thoracic cavity (the diaphragm flattens when it contracts, remember?). Increasing volume of a closed cavity decreases pressure, the outside pressure wants to flow into the low pressure area,and the airway and lungs make a handy, dandy place for the outside air to come in. The lungs expand to equalize the pressure (the lungs expand in volume to essentially match the expansion of volume created by the diapragm).

There's a cause and effect. It's really, really basic physics and anatomy and that's what really happens. Read the Wikipedia article again (it's taken from an old Gray's Anatomy book, but is still accurate). If you can't get by the 1st order effects then worry about second order (intracostals, etc.) is going to be a red herring.
