A long flat muscle that extends along the whole length of both sides of the abdomen. It flexes the vertebral column, particularly the lumbar portion; it also tenses the anterior abdominal wall and assists in compressing the abdominal contents. It is frequently the site of hematomas. In PLASTIC SURGERY PROCEDURES it is often used for the creation of MYOCUTANEOUS FLAP. (From Gray's Anatomy, 30th American ed, p491)
