The shoulder joint with muscle ligament model is a biological teaching tool used to demonstrate the complex structure of the shoulder joint and the anatomical relationships of the surrounding muscles and ligaments. This model simulates the shape of the real shoulder joint, including the glenoid of the humeral head and scapula, the joint capsule, and the rotator cuff muscle group. In biology teaching, this model can help students intuitively understand the composition and function of the shoulder joint, and learn how the shoulder joint achieves multi axial movement through the synergistic effect of muscles and ligaments. By observing the model, students can master the anatomical structure of the shoulder joint and understand its stability and flexibility.
