Oct 30, 2023 · The ascending (lower) part is supplied by muscular branches of the dorsal scapular artery, which arises from the subclavian artery. The main function of the trapezius is stabilizing the scapula in its anatomical place, as well as controlling it during movements of the shoulder and upper limb.

The trapezius is a broad, flat, superficial muscle extending from the cervical to thoracic region on the posterior aspect of the neck and trunk. The human trapezius muscle has an origin that is more extensive than that of any other body muscle.

Oct 30, 2019 · The lower trapezius (G. trapeza, four-sided or four-legged table.) is not an individual muscle, itself, but rather it is the lowermost section of fibers in the trapezius muscle. It acts on the scapula, with its main role as the prime mover in scapular depression.

Jun 25, 2024 · “The trapezius — which consists of an upper, middle, and lower trap — helps bring the shoulder girdle down, which stabilizes the spine and promotes good posture,” says Sarah Kellen, PT, DPT, a physical therapist at Hinge Health.

Each trapezius muscle has three sections: The upper (superior) section. The middle section. The lower (inferior) section. Your traps connect to your skull, spine, ribs and bones in your shoulders.

Nov 7, 2023 · The lower or inferior portion courses upwards laterally and converge into an aponeurosis near the scapula. It then passes over the scapular spine to insert into a tubercle at the lateral apex of its medial end.

Oct 4, 2024 · The lower trapezius extends from the mid to lower thoracic vertebrae and attaches to the spine of the scapula. Its main role is to depress the scapula, pulling it downward and stabilizing it during arm movements. This part of the trapezius is particularly important for activities that involve pulling motions, such as rowing or climbing.

Jun 29, 2023 · Finally, the lower trapezius muscle is tasked with the upper and mid-spine stabilizing action of bringing the shoulder girdle down. This is the opposite action to that of the upper trapezius. The trapezius is an accessory breathing muscle. This means that it helps open up a small amount of breathing room in the upper chest area.

Mar 28, 2024 · Training the trapezius muscles, which extend from the back of your neck and shoulders down to the middle of the back, is vital for several reasons: strength and function, posture, aesthetics, and injury prevention. This article reviews ten of …

The trapezius [4] is a large paired trapezoid-shaped surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm. The trapezius has three functional parts:
