I think it's your elbow.
Ball and socket type of joint allow adduction, abduction,flex-ion,extent-ion andcircumduction.Shoulder and hip joints are the examples of ball and socket joint.

What types of movement joints are required in a concrete masonry wall
Joints are located where two bones connect. They allow movement and provide mechanical support.
Fused joints, the type found in the cranium, don't provide any movement. They are called immovable joints for this reason.
These are called immovable joints.
Diarthrotic joints have free movement e.g. synovial joints of knee, elbow, shoulder synarthrotic = no movement eg skull plates (yes they are a type of joint strangely enough) amphiarthrotic = some movement eg intervertebral discs
Synarthroses are joints that do not move, such as those that connect the bones of the skull.
# Hinge joints allow movement in one direction, as seen in the knees and elbows. # Pivot joints allow a rotating or twisting motion, like that of the head moving from side to side. # Ball-and-socket joints allow the greatest freedom of movement. The hips and shoulders have this type of joint, in which the round end of a long bone fits into the hollow of another bone.
freely moveable joints

The thumbs have saddle type joints, which allow the thumb to oppose the palm, but the most freely movable joints are the ball and socket joints of the hips and shoulders.

Fused joints, the type found in the cranium, don't provide any movement. They are called immovable joints for this reason.
Joints which allow very little or no movement are called fibrous joints (joints held together by fibrous connective tissue).There are three types of fibrous joints:Sutures are the seams that join the bones of the cranium.Gomphoses are fibrous joints in the shape of a socket such as where the teeth attach to the jaw. These are the only Gomophose joints in the human body.Syndesmoses are fibrous joints which allow a very small amount of movement due to interosseous membranes or ligaments connecting the bones. The place where the tibia and fibula (bones of the lower leg) join at the ankle is a Syndesmosis joint.
you oviously use the joints in your knees and the motion of your hips to propel the movement of your legs
These are called immovable joints.
