A special centre in the medulla region of the brain is primarily responsible for regulating respiratory rhythms. This is the ‘Respiratory Rhythm Center’. This centre produces rhythmic nerve impulses that contract the muscles responsible for inspiration (diaphragm and external intercostal muscles). Normally, expiration happens when these muscles relax. However, in case of rapid breathing, this centre stimulates the muscles responsible for expiration (internal intercostal muscles and abdominal muscles).
