What are the proper medical names for these joints?
Hello! I am making a model arm for Human Anatomy, and I have already completed the model, but I need to complete a worksheet with the proper medical terms for the following joints:
Shoulder Joint
Elbow Joint
Proximal Joint (of the radius and ulna)
Distal Joint (of the radius and ulna)
When I say medical names I do not mean ball-and socket (that’s the synovial joint). I mean the true medical names. Any help will be greatly appreciated! Thank you! (:

The shoulder has four joints (three anatomical, one physiologic). I think you’re looking for the glenohumeral joint, which is between the humerus and the scapula. The elbow has two joints, but the primary is the humeroulnar joint between the humerus and the ulna. The joints between the radius and ulna are called the proximal radioulnar and distal radioulnar joints.
For a sense of accuracy, you should realize that all of these are synovial joints. The ball and socket is just a specific subtype. The only nonsynovial joint in the shoulder is the scapulothoracic joint, which is not even between two bones. It’s a junction formed by muscles attaching to the scapula and the thoracic cage.
