Ball-and-socket joint (art. Spheroidea) (e.g. the shoulder joint). One of the articular surfaces forms a convex spherical head, the other—a correspondingly concave articular cavity. Theoretically, movements can occur on many axes which correspond to the radii of a sphere. Practically, however, only the following three main axes, perpendicular to each other and intersecting in the centre of the head, are distinguished: (1) the transverse (frontal) axis, the site of forward flexion, anteflexion, when the moving part together with the frontal plane forms an angle open to the front, and of backward flexion, Medical Coding Services will help in the coding services.
