Mm. intercostales, Mm. scaleni und M. transversus thoracis
The muscles Mm. intercostales and M. transversus thoracis belong to the autochthonous chest muscles, which are an important part of the respiratory muscles. The Mm. scaleni belong to the deep neck muscles. As they function as auxiliary breathing muscles, they are also explained here.
A schematic drawing of the muscles (Mm. intercostales, Mm. scaleni and M. transversus thoracis) can be displayed by clicking on the respective name in the "WebViewer".
