The scalenes are a group of muscles located in your neck. They are composed of three different muscles: the anterior scalene, the middle scalene, and the posterior scalene. These muscles run on each side of your neck, extending from the cervical vertebrae (the bones of the neck) to the first and second ribs.
Their main role is to help with the breathing process. The scalenes elevate the first two ribs when you inhale deeply, which aids in expanding your chest to draw more air into your lungs. Additionally, they play a crucial role in the movement of the neck. They assist in tilting your head to the side and can also help in rotating your neck. This is particularly useful in many daily activities and sports that require precise and flexible neck movements.
Due to their position and function, the scalenes are also involved in posture. They help maintain the alignment of the neck and contribute to a balanced posture. This is essential not only for general health and comfort but also for effective performance in various sports and activities.
However, the scalenes can become tight or strained due to factors like poor posture, especially in people who sit for long periods or frequently use computers and mobile devices. When this happens, it can lead to discomfort or pain in the neck, shoulders, and upper back. It might also cause issues like tingling or numbness in the arms, as tight scalene muscles can sometimes put pressure on nearby nerves.
To keep the scalenes healthy, it is important to practice good posture, take regular breaks from sitting, and incorporate stretching and strengthening exercises for the neck. This will help ensure these muscles function properly, supporting your neck, enhancing your breathing, and contributing to overall muscular balance.
