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".
autochthonous chest muscles - Mm. intercostales und M. transversus thoracis
| Mm. intercostales externi | Mm. intercostales interni | M. transversus thoracis | |
| origin | Lower margin of a rib (Tuberculum costae up to Cartilage-bone junction) | upper margin of a rib (Angulus costae to Sternum) | inside rib cartilage of 2nd-6th rib |
| insertion | upper margin of next deeper rib progression: from posterior top to posterior bottom (Tuberculum costae to cartilage-bone junction) |
lower edge of next highest rib progression: from back bottom to front top (Angulus costae to sternum) |
Inside of Corpus sterni and Processus xiphoideus sterni |
| function | rib lifter (inspiration), tighten the interrib spaces; stabilization of the thoracic wall |
rib countersink (expiration); tighten the interrib spaces; stabilization of the thoracic wall |
Rib countersink (expiration) |
| innervation | Nervi intercostales 1-11 | Nervi intercostales 1-11 | Nervi intercostales 2-6 |
