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.
