Internal Oblique Anatomy: Origin, Insertion & Action

⭐ Internal Oblique Muscle Anatomy ⭐
💪Origin: Thoracolumbar fascia, iliac crest and the inguinal ligament
💪Insertion: Inferior margins of tenth to twelfth ribs and adjacent costal cartilages, linea alba and the pectineal line
💪Action: Lateral flexion of the torso (unilateral contraction), rotation of the torso (unilateral contraction) and flexion of the torso (bilateral contraction)
💪Nerve: Anterior rami of intercostal nerves (T7-T11), subcostal nerve (T12), iliohypogastric nerve (L1) and the ilioinguinal nerve (L1)

How does external oblique muscle rotate trunk to the opposite when doing unilateral movement? Shouldnt internal muscle do rotation to the opposite side because it has insertion in the ribs?
