The major natural source of the vitamin is synthesis of cholecalciferol in the Adduction also occurs at the vocal cords and in the neck; however, the medical term for neck adduction is lateral flexion. Plane joints, sometimes called gliding joints and shown as letter D on the diagram, are probably the most difficult joint type to visualize. Saddle joints, indicated by letter C in our illustration, are similar to hinge joints but provide more range of motion. A simple way to remember adduction versus abduction is that by moving a limb inward toward the midline, the adduction movement is ''add''ing to the body.

Muscle architecture is the physical arrangement of muscle fibers at the macroscopic level that determines a muscles mechanical function. First, it must include two bones that meet together. In the case of a saddle joint, the bone sitting on the saddle can move in an oval shape relative to the other bone. The type of movement that can be produced at a synovial joint is determined by its structural type. Summation of these vectors is Atrophy is the wasting away of the body or of an organ or part from such issues as poor nutrition, nerve damage, degeneration, decline, or decrease, as from disuse, or disease. An imaginary line cutting the body in half into distal and proximal (top to bottom) segments is called the transverse plane.
