Sternocleidomastoid and Breathing *EXPLAINED*

The sternocleidomastoid is a muscle located in the neck that plays a key role in breathing. When we inhale, the sternocleidomastoid contracts and helps lift the ribcage to create more space in the chest cavity for the lungs to expand. This muscle also works in conjunction with other respiratory muscles to assist in the process of breathing. Additionally, the sternocleidomastoid is involved in turning and tilting the head, which can further aid in improving airflow during breathing. Overall, the sternocleidomastoid is an important muscle for proper breathing mechanics and overall respiratory function.
