The scapula, or shoulder blade, is a big, level triangular bone that rests at the rear of the shoulder. The 3 muscle mass that comprise the scapula are the trapezius, latissimus dorsi, as well as pectoralis significant. These muscle mass interact to relocate the arm as well as maintain the shoulder joint.
The trapezius is the biggest of the 3 muscular tissues and also prolongs from the base of the neck to the reduced back. It is accountable for relocating the scapula up, down, and also laterally.
The latissimus dorsi is a huge muscular tissue that expands from the reduced back to the arm. It aids to relocate the arm backwards as well as downward.
The pectoralis significant is a wide muscular tissue that covers much of the upper body.
