The external oblique muscle is one of the outermost abdominal muscles, extending from the lower half of the ribs around and down to the pelvis.Together, the external oblique muscles cover the sides of the abdominal area, being large and sitting on the top surface of the abdomen right below the subcutaneous fat and skin. In most humans (especially females), the oblique is not visible, due to subcutaneous fat deposits and the small size of . The internal oblique inserts by an aponeurosis on the linea alba. The muscles that produce the opposite movement, which is back flexion, are the abdominals. The concentric contractions of the ipsilateral internal oblique and the contralateral external oblique are balanced by the eccentric contractions of the contralateral internal oblique, ipsilateral external oblique, abdominals and erector spinae to rotate the trunk. The internal oblique is an abdominal muscle located beneath the external abdominal oblique. It is broad and thin. In left bending from standing position, in scoliosis group, the antagonistic activity of EST6 muscle was greater than its agonistic activity (p<0.05). The muscles opposing the movement become the antagonists. These muscles help pull the chest, as a whole, downwards, which compresses the abdominal cavity. external and internal obliques.
