A ball and socket joint (enarthrosis, spheroidal joint) is a joint in which the distal bone is capable of motion around an indefinite number of axes, which have one common center. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Introduction ( Joints or Articulations Sutural ligament Fibrocartilages Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group A joint is the location at which two or more Bones make contact It helps the bone to move in a 360o angle.
In a ball and socket (or spheroid) joint, the ball-shaped surface of one bone fits into the cuplike depression of another.
The ball and socket joint is a movable joint, that consists of one bone that is rounded and that fits within a cuplike bone.
Movements possible are flexion-extension, abduction-adduction, rotation (triaxial) and circumduction. In Anatomy, flexion is a position that is made possible by the joint angle decreasing Extension is a movement of a joint that results in increased angle between two bones or body surfaces at a joint Abduction, in functional anatomy is a movement which draws a limb away from the median ( Sagittal) plane of the body Adduction is a movement which brings a limb — Arm or Leg — closer to the sagittal plane of the body A rotation is a movement of an object in a circular motion A two- Dimensional object rotates around a center (or point) of rotation
