The two bones that make up the lower arm, or forearm, are called the radius and the ulna. The radius is the bone that is located on the thumb side of the forearm. The ulna is the bone that is located on the pinky side of the forearm.
The scapula and the upper arm bone meet at the glenohumeral joint, also known as the shoulder joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation of the arm.
Ball-and-Socket, the shoulder's cartilage being the socket and the arm's ending being the ball.
External rotation of the arm at the shoulder joint refers to the movement where the arm rotates outward away from the body. This motion occurs when the shoulder joint allows the arm to move in a way that the palm faces forward or upward. It is an important movement in various activities like throwing a ball or reaching behind the body.
The medial roataion is the movement of Glenohumeral joint .
The radioulnar joint allows for rotation of the wrist. This joint is formed by the articulation of the radius and ulna bones in the forearm. Rotation at this joint is responsible for movements like pronation and supination of the hand.

Your shoulder joint allows you to raise your arm above your head.
The upward rotation of scapula muscles helps to stabilize the shoulder joint and allows for smooth movement of the arm.
The ball-and-socket joint of the shoulder allows the upper arm to be raised and lowered.

ball and socket joint
The synovial joint between the scapula and the humerus is a ball-and-socket joint. This joint allows for a wide range of motion, including rotation and circumduction of the arm. It is known as the glenohumeral joint.
The medial roataion is the movement of Glenohumeral joint .
Ellipsoid joint
We tend to use them to mean the same thing. In two dimensions, a simple support is one that allows rotation. A pin joint support is a simple support that allows rotation but not translation. A roller joint support is a simple support that allows rotation and translation.
