1. A ball %26 socket joint has 3 degrees of motion compared to a hinge joint %26 saddle which has 2 degrees of motion. A gliding joint has only one degree of motion. In other words, a ball %26 socket joint like the hip and shoulder joints can do triplanar motion namely abduction/adduction, flexion/extension and rotation.

2. Both of them refer to a disease process. Osteopathy (osteo=bone, pathy=pathology) and myocardosis (myo=muscle, cardio=heart, osis=condition).
