The main muscles of inspiration are the diaphragm, external intercostal muscles, and parasternal intercartilaginous muscles. However, the diaphragm is probably the single most important muscle. The accessory muscles of inspiration are the sternocleidomastoid and scalenus. Unforced expiration is a passive process and requires relaxation of the above muscles. Forced expiration requires the internal intercostal muscles, rectus abdominis, external oblique, internal oblique and the transversus abdominis.

The lungs are inflated and deflated by the movements of the ribcage (unless you are a professional singer and use your diaphram). The Intercostal Muscles which lie between the ribs cause the ribcage to rise and fall.
