The respiration control center is in the medulla, which itself is in the lower part of the brain stem. Within the medulla are neurones, which are specialized breathing cells. There are two types of neurones: inspiratory an expiratory. Inspiratory neurones are active during inhaling.
Respiration is controlled by centres in the medulla, which influence the rate of breathing and the depth of each breath. 1  This is influenced by the blood level of carbon dioxide, as determined by central and peripheral chemoreceptors located in the central nervous system and carotid and aortic bodies, respectively.
