Ball and socket joint
Sliding
The joints connects the arm to the upper body.
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.
None. Because the wrist is the joint of the arm and the hand.
The shoulder joint is one of synovial (means a joint which is covered by a membrane named synovial) joints this means it allows movement freely unlike other joints such as suture lines of your skull. It's also called ball and socket type of joint means the head of humerus ( a bone of your arm) is inside a large cavity of your scapula ( a bone of your shoulder).
Without joints, we would be immobile.
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
your arm and hips are one of them
your arm and hips are one of them
flexing is tightening of your muscles, and joints bend to let you extend your arm from the elbow and shoulder
your arm and hips are one of them
You would not be able to eat (jaw joints) or move (arm, leg, and neck joints).
The degree of freedom (DOF) of a robotic arm can be computed based on the number of the joints and types of the joints. For most robotic arm, the joint is either prismatic or revolute(about one axis), the DOF is simply the total number of the joints.
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.)
