trapeziuslihaksen

Trapeziuslihaksen, commonly known as the trapezius muscle, is a large paired muscle of the upper back and neck. It originates from the external occipital protuberance and nuchal ligament of the skull and inserts along the entire length of the clavicle and scapula. This broad muscle is divided into three distinct parts: the upper, middle, and lower trapezius.

The upper trapezius is responsible for elevating the scapula, such as when shrugging the shoulders, and also assists in rotating the head and neck to the opposite side. The middle trapezius primarily retracts the scapula, pulling the shoulder blades together. The lower trapezius depresses the scapula and also contributes to its upward rotation.

The trapezius muscle plays a crucial role in maintaining posture, supporting the arms, and enabling a wide range of movements of the head, neck, and shoulders. It is often affected by stress and poor posture, leading to tightness and pain. Stretching and strengthening exercises for the trapezius are frequently recommended for individuals experiencing discomfort or seeking to improve their upper body function. Its prominence makes it a visible muscle, often targeted in athletic training and therapeutic interventions.
