Überblick über die Muskeln der Rumpfwand

This video tutorial provides a comprehensive overview of the torso wall muscles, focusing on the chest, abdominal, and back muscles. It details the functions of intercostal muscles, neck and chest muscles, and the role of abdominal wall muscles in respiration and movement. The tutorial also covers the back and dorsal abdominal wall muscles, highlighting their importance in stabilizing the spine and aiding in respiration. Finally, it introduces the autochthonous back muscles, explaining their structure and function in supporting the spine.
