Funktion

• Laterally flexes the spine..

  This means that the internal oblique muscle bends the spine to the side (i.e. it moves the ribcage downward to the side towards the pelvis).

• Rotates the spine..

  This means that the internal oblique muscle turns the spine to the side (i.e. it twists the torso).

• Compresses the abdominal cavity..

  This means that the internal oblique muscle constricts the organs of the abdominal cavity and can increase intra-abdominal pressure (i.e. such as during a valsalva maneuver).
