The internal intercostal muscles work to pull the ribs closer together during exhalation, while the external intercostals work to lift the ribs during inhalation. The scalenes and sternocleidomastoids are accessory muscles involved in elevating the rib cage during forced inhalation, but they do not specifically pull the ribs closer together.
