The external oblique muscles originate from the fifth to the twelfth ribs. They are situated on the sides of the abdomen and play a crucial role in trunk rotation and lateral flexion. The fibers of these muscles run diagonally downward and medially, contributing to the overall structure and function of the abdominal wall.
