THE APPENDICULAR SKELETON The appendicular skeleton is made up of the skeletal elements of the upper and lower members (often incorrectly referred to as the “extremities”). These members are appended (attached) to the axial skeleton. The general pattern of construction of the upper and lower members is the same as follows: Girdle. The girdle is the actual attaching part. It attaches (appends) the limb (the member less the girdle) to the axial skeleton. Proximal limb segment. The proximal segment of the limb has a single long bone. Middle limb segment. The middle segment of the limb has two long bones parallel with each other. Distal limb segment.
