Which of the following bones facilitate movement of the chest during both inspiration and expiration?

The clavicle articulates with the manubrium of the sternum at the sternoclavicular joint, which is the sole bony link between the upper extremity and the axial skeleton. As the thoracic cage expands during inspiration - particularly with upper chest breathing - the clavicle elevates and protracts; during expiration it depresses and retracts, meaning it moves in direct mechanical response to chest wall dynamics throughout the respiratory cycle.

The scapula has no direct bony articulation with the ribcage and moves primarily in response to shoulder girdle activity rather than facilitating the mechanical expansion and compression of the chest during breathing.

The carpal bones are located in the wrist and have no anatomical connection to the thoracic cage or respiratory mechanics whatsoever.

The scalenes are a group of skeletal muscles of the lateral neck that act as accessory respiratory muscles by elevating the upper ribs during forced inspiration; they are not bones and therefore cannot be the correct answer to a question about bones.
