Diaphragm Anatomy

Anatomy of the Diaphragm Muscle
The diaphragm is the major abdominal muscle that is involved in the breathing process.  The surrounding abdominal muscles support the diaphragm in its actions.  When at rest, the diaphragm forms a high arched dome.  When it contracts, the dome descends, increasing the height of the chest cavity, resulting in air being drawn into the lungs.  This contraction is directly correlated to the process that we know as inspiration or breathing in.
