Not everyoneâs ânormalâ body temperature is the same. Yours could be a whole degree different than someone elseâs. A German doctor in the 19 th century set the standard at 98.6 F, but more recent studies say the baseline for most people is closer to 98.2 F.
The pelvic floor muscles form the base of the group of muscles commonly called the âcoreâ. These muscles work with the deep abdominal (tummy) and back muscles and the diaphragm (breathing muscle) to support the spine and control the pressure inside the abdomen.
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.
