To assess the characteristics and function of the muscles of the anterolateral abdominal wall, we have examined the isometric contractile properties of bundles of canine rectus abdominis (RA) and external oblique (EO) muscles. In addition, we have related the lengths of these muscles measured sonometrically in vivo at supine functional residual capacity (FRC) to in vitro optimal force-producing length (Lo). We also investigated the action of the abdominal muscles on the displacement of costal… CONTINUE READING
