The scalenes consist of three muscles: anterior, middle, and posterior scalene. They are located on the side of the neck and originate from the cervical vertebrae, inserting into the first and second ribs. They flex and laterally flex the neck, and also assist in breathing by elevating the ribs. Tight scalenes can cause neck pain and contribute to thoracic outlet syndrome.
