I think it might be a ball and socket joint of a universal joint.
The articulating bones in the shoulder are the humerus, scapula, and clavicle. These bones come together to form the shoulder joint, also known as the glenohumeral joint, which allows for a wide range of motion in the shoulder.
The Clavicle and Scapula
There are 2 bones in your forearm. The ulna and radius. They are connected at the parietal end to the humerus forming your elbow and at the distal end to the carpals forming your wrist.
The scapula articulates with the humerus to form the ball and socket joint at the shoulder, known as the glenohumeral joint. This joint allows for a wide range of motion in the shoulder.
The clavicle (collarbone) and the humerus (upper arm bone) are attached to the scapula (shoulder blade) to form the shoulder joint.
The shoulder girdle is actually the clavicle scapula and top of sternum. The bony process at top of shoulder is the acromion process which connects with the spine of the scapula. The joint between this and the clavicle is known as the AC joint (Acromioclavicular). These bones make up the shoulder girdle
No, the humerus is a bone in the upper arm and forms part of the shoulder and elbow joints. It is not a joint itself but rather connects to other bones to form movable joints.
A joint that does not allow any movement is called a synarthrosis joint. This type of joint can be found in the skull, where two bones have a suture line that is immovable. An example is the joint between the two parietal bones of the skull.
Where two bones come together or "join" is called a "joint".
it is arthritis in the shoulder joint, the collarbone (clavicle), the shoulder blade , and the arm bone . The scapula and clavicle form the socket of the joint The humerus has a round head that fits within this socket. The end of the scapula is called the acromion, and the joint between this part of the scapula and clavicle is called the acromio-clavicular joint, or AC joint. When this joint wears thin, it is called acromioclavicular (or AC) arthritis.
Muscles that brings the two (or more) bones that form it closer are called flexors.
