This increases thoracic volume in a vertical direction. Inspiration is aided by contraction of the parasternal and external intercostals, which raise the ribs when they contract and increase thoracic volume laterally. Other thoracic muscles become involved in forced (deep) inspiration.
More about the breathing muscles. The left side of figure 1 shows the muscles involved with taking a breath in (inspiration). As previously mentioned, the diaphragm is the main muscle responsible for this.There are also muscles of the neck, which are supplied by the cervical nerves, which assist breathing in. The rib muscles or intercostals also work in co-operation with the diaphragm.n general breathing out is passive and requires no muscle effort, but occasionally we need to exhale forcefully, for example when coughing, throat clearing, shouting or blowing our nose. It is during these times of forceful breathing out that the stomach and rib (intercostal) muscles are used.
