The shoulder is the many flexible joint in the huguy body. It is likewise among the most complicated, via a better variety of movement than any type of various other joint. It permits us to raise, bfinish, rotate and swing our arms. A correctly functioning shoulder is not just critical to the golf game, but to many kind of tasks of everyday living.
You are watching: Which joint is considered the most flexible joint in the body?
The shoulder is our many mobile, yet leastern secure joint. Its significant variety of motion makes the shoulder much less secure, and also it is mostly even more vulnerable to injury and dislocation than our various other joints.
The shoulder is made up of 3 bones: the upper arm bone (humerus), the shoulder blade (scapula) and also the collarbone (clavicle).
These bones are joined together by muscles, ligaments and tendons that support and stabilize the shoulder, permitting the arm to feature.
The shoulder is composed of 4 joints:The glenohumeral joint is the major joint of the shoulder. It is wbelow the rounded top part of the arm bone, the humeral head or "ball", meets the "socket" (glenoid) of the shoulder blade. This joint is described as a "ball and also socket" joint in terms of its form and also function. The joint surfaces communicate in a manner comparable to a golf round on a tee. The socket is extremely shenable and also smaller than the ball, therefore the joint is inherently much less stable than a true sphere and deep socket, such as the hip joint. The sternoclavicular joint is the joint in between the sternum (chest bone) and also collar bones.The acromioclavicular joint, generally referred to as the AC joint, is wbelow the collarbone meets the highest possible point of the shoulder blade (acromion).The scapulothoracic joint is in between the rib cage and the shoulder blade
Shoulder Joint and Ligaments
Several necessary ligaments can be found in the shoulder joints. The major attribute of the ligaments is to provide stability to the naturally unsecure joint and also to strengthen the capsule that surrounds the shoulder.
Many kind of muscles are responsible for motion in the shoulder, but the primary muscle groups are the rotator cuff, the deltoid and also the trapezius.
The rotator cuff is a group of muscles and also their tendons that connect our upper arm to our shoulder blade. The many vital task of the rotator cuff muscles is to carry out stcapability for the ball (the end of the top arm bone) in the socket and particularly center the round within the socket throughout useful activities. The rotator cuff is also responsible for lifting the arm out to the side, as well as exterior and internal rotation of the shoulder.
The deltoid muscle team is responsible for shoulder flexion (increasing our arm straight out in front), abduction (elevating our arm directly out to the side), and also extfinishing our arm behind our ago.
The trapezius is a huge kite-shaped team of muscles extfinishing from the low ago to the neck. These muscles, recognized as "traps", are divided into an upper, middle and also lower percentage and occupational together with other muscles on the joints of the shoulder. The top traps elevate the shoulder (shrug), the middle traps retract the shoulder (shoulder blade squeeze) and the lower traps depush the shoulder (shoulder blade puburned downward).
Normal Range of Motion
The normal array of movement of the shoulder deserve to vary. A golfer that lacks normal selection of activity might be at greater danger of shoulder injuries.
