[2] Inspiratory crackles may be heard on exam. It may be of physiological, pathological or social origin. Dyspnoea is often hard to diagnose and treat since several different causes can occur. As the brain receives its plentiful supply of afferent information relating to ventilation, it is able to compare it to the current level of respiration as determined by the efferent signals. [2] It is the most common lung disease in both developing and developed countries affecting about 5% of the population. Other respiratory muscles include the external and internal intercostal muscles, the abdominal muscles and the accessory breathing muscles. (eds)) (16th ed.).
