Neck muscles are a group of muscles that support and move the head. They play a crucial role in maintaining posture and allowing for various movements, such as turning and tilting the head. Key neck muscles include the sternocleidomastoid, which helps rotate the head, and the trapezius, which supports the shoulders and upper back. These muscles are essential for everyday activities, including looking around, nodding, and even swallowing. Proper neck muscle function is important for overall mobility and can help prevent pain or injury. Strengthening and stretching these muscles can improve flexibility and reduce tension.
