What is a common function of the scalene muscles?

The scalene muscles, which are located on the lateral sides of the neck, have a primary function that involves neck flexion and rotation. When these muscles contract, they assist in flexing the neck forward and can also facilitate lateral flexion and rotation to the opposite side. This means that when one side of the scalene muscles contracts, it helps to bend the head toward the shoulder of the opposite side. Additionally, they play a key role in the respiratory process, as they help elevate the first and second ribs during inhalation, which can inadvertently contribute to the overall stabilizing and functional movement of the neck. The involvement of the scalene muscles in neck movements is essential for maintaining proper posture, supporting head movements, and aiding in respiratory function.
