Mysteries of the Shoulder Joint
The shoulder is an essential part of the body. It is used to throw things and lift things above the head. It’s also used to swing a golf club. Without the shoulder, none of these motions would be possible.
Animals have shoulder joints as well. The function of the shoulder in animal is different, however. The goat shoulder, for example, supports the weight of the goat as it walks. Here’s more interesting facts about the shoulder.
The Shoulder Consists of a Ball and Socket Joint
In a ball and joint socket, the end of one bone is shaped like a ball and the end of the other bone is shaped like a cup. Both ends meet to form the joint. In the shoulder, this joint is known as the glenohumeral joint. Ball and socket joints have the greatest range of motion.
The Shoulder Relies on the Rotator Cuff
The rotator cuff is a series of muscles and tendons that support the shoulder. These muscles connect the scapula to the humerus. When these tissues are injured, it can be very painful to move the arm. The tendons are usually torn while playing sports. Baseball pitchers usually injure their rotator cuff while throwing a baseball. Weight lifters can also injure the rotator cuff. So can water polo players.
Rotator cuff injuries are usually treated with rest, ice, surgery, or physical therapy. Rehab is usually needed to strengthen the muscles and improve the range of motion of the joint.
The Rotator Interval is Interesting
There is a triangular space in the shoulder that is supported by tendons differently. One supports the space externally, one supports it internally, and the last one traverses it.
Animal Shoulders vs Human Shoulders
Animal shoulders are different from human shoulders. For example, the goat shoulder has a smaller range of motion than human shoulders. The goat shoulder isn’t as complex. The goat shoulder has a different function than the human shoulder. The goat shoulder is used to move and to support the weight of the body. Animal shoulders are also eaten. Goat shoulder is prepared as a stew and eaten in Africa and Asia.
