Anatomical illustration of trapezius muscles. If you are not clear, come and learn.

Trapezoidal muscles are located on the surface muscles of the upper and middle dorsal. Of course, there are many functions of trapezoidal muscles, such as connecting the shoulder strap bones to the skull base and vertebrae, and suspending the shoulder strap bones. So, what is the anatomical illustration of trapezoidal muscles? Let’s take you to understand trapezoidal muscles. Let’s take a look!

　　Trapezoidal muscles (42 muscle anatomies, let’s learn about trapezoidal muscles.)

　　Traezoidal muscles are the surface muscles located on the upper and middle dorsal, located under the skin of the neck and back, one side is triangular, and the left and right sides are combined into a trapezoidal shape.

　　Traezoidal muscles connect the shoulder strap bones to the skull base and vertebrae The fibers are divided into three parts: upper, middle and lower, and end at 1/3 of the lateral clavicle, scapula and acromion.

　　After near fixation, the upper fibers contract, which causes the scapula to lift, circle, and retract; the middle fibers contract, which causes the scapula to shrink and circle; the lower fibers contract, which causes the scapula to descend and circle.

　　When the distant fixation is, one side contracts, which causes the head to flex to the ipsilaterally and circle to the opposite side; both sides contract, which causes the head and spine to straighten.

　　Developing this muscle in childhood can prevent and correct hunchback.

　How to practice trapezius (trapezoidalis muscles) Anatomical explanation will let you know the detailed knowledge of trapezoid muscles.)

　　1. Dumbbell shrugged

　　First open the legs, hold the dumbbells in both hands next to the body, and the fist is facing forward. After taking a deep breath, you must hold your breath and let the trapezoid muscles shrug your shoulders upwards by contracting. Next, wait until the shoulders reach the highest point, and then exhale for two or three seconds to slowly weaken the control of trapezoid muscles and change back to their original position. Use a little force when shrugging vertically, but the speed should be slower. Only after both arms are straightened, the elbow joints cannot be bent.

2. Barbell shrugged

　　After the legs are spread, open the shoulders, then hold the barbell at a medium width and place it in front of your thighs. And the hands should be held back. After doing these movements, raise your head, look forward, raise the barbell and shrugged.
