In human physiology, the muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity.The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.Additional 'accessory muscles of respiration' are typically only used under conditions of high metabolic demand (e.g. exercise) or respiratory dysfunction (e.g. an asthma attack).dditional 'accessory muscles of respiration' are typically only used under conditions of high metabolic demand (e.g. exercise) or respiratory dysfunction (e.g. an asthma attack).
The Muscles of Respiration. Please look closely at this illustration by the great anatomical illustrator Netter, and see what you can learn from it. Note that the muscles marked with blue arrows on the left side of the image are the muscles involved in inspiration (breathing in).xpiration, the caption says, results from passive, elastic recoil of the lungs, rib cage and diaphragm.. Note that in the Sounder Sleep System, all the breathing we do is quiet breathing only. In active breathing, certain muscles are activated on exhalation.
