Here is the entire list:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)Diaphragm (Prime mover of inhalation)When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
