During inspiration, the primary muscles involved are the diaphragm and intercostal muscles. Muscles not involved in this process include the abdominal muscles and certain back muscles, such as the latissimus dorsi, which primarily assist with other movements rather than inhalation. Additionally, while accessory muscles like the sternocleidomastoid and scalene muscles may aid in deep or labored breathing, they are not required for normal inspiration. Thus, many core and upper body muscles do not play a direct role in the act of inhaling.
