Hands may move and be positioned in a variety of positions thanks to the human appendage arm. It should be obvious that we require our hand to be positioned in a variety of positions in order to perform our physical activities. As a result, our shoulder is quite flexible, allowing us to articulate our hand in a variety of positions. However, the drawbacks of this flexibility are instability and reduced strength. Because ligaments (which connect two bones), tendons (which connect a bone to a muscle), and muscle are three major cardinal components of our shoulder, it is frequently referred to as a soft tissue. Physiotherapy is the only treatment option for any type of shoulder problem.You can learn this here now
The “glenoid” surface of the shoulder blade in the upper appendicle skeleton forms a ball and socket joint with the ball-like spherical head of the humerus. Many tendons protrude from the head of the humerus, which unite in the glenoid cavity to support the shoulder joint and allow multidimensional mobility.
The head of the humerus is larger than the glenoid cavity that received it to create the shoulder joint, but the glenoid cavity’s rim has a layer of fibro cartilage that cushions and accommodates the humerus, stabilises the joint, and pushes and wraps the inserted humerus. The clavicle (beauty bone) and the shoulder blade create a joint called the acromino clavicular joint, which is located above the shoulder joint. The ball and socket joint beneath it is stabilised by this joint.
