socket and ball
Two main joints in the human body are the knee joint, which allows for bending and straightening of the leg, and the shoulder joint, which enables a wide range of motion in the arm.
A ball and socket joint allows the arms to move in a circular motion. A ball and socket joint is also called an spheroidal joint.
Without joints, we would be immobile.
The elbow and knee joints are hinge joints, allowing movement in a single plane (flexion and extension). This design enables the joints to bend and straighten, facilitating basic movements like bending and straightening the arm or leg.
None. Because the wrist is the joint of the arm and the hand.
Your shoulder joint allows you to raise your arm above your head.
The ball and socket joints allows flexible movement of the arm in all directions.
Move your arm in circles

To improve arm strength and flexibility, aim to do 15-20 arm circles in each direction daily.

If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
Cartilaginous are slightly movable, but the most prominent type of movable joints are synovial joints, such as the knee and shoulder, which are very movable.

You would not be able to eat (jaw joints) or move (arm, leg, and neck joints).
