Definition. Oblique muscle refers to two abdominal muscles - the external and internal obliques. These provide trunk flexion and rotation. The external oblique is the thickest and runs from the lower ribs to the iliac crest. The internal oblique lies under the external muscle and also originates at the iliac crest before reaching the pubic bone.

The internal oblique muscle originates from the anterior two-thirds of the iliac crest and the thoracolumbar fascia. Its fibers diverge over the side of the trunk and insert along the structures of the midline, including the inferior margins of ribs 10-12, the linea alba, and the pubic crest.

The internal obliques can function bilaterally, which means both sides work together. Bilaterally they flex the trunk and compress its contents. They can also function unilaterally, which means one-sided. Unilaterally, they laterally flex the trunk and rotate it to the same side. Like the internal obliques, the external obliques function.
