Appendicular skeleton - Girdles Girdles (6) help to articulate the limb bones to the main axial skeleton. This bone has a roughly triangular shape. Hence bones of forelimb and hindlimb is an example of the appendicular skeleton. Figure 7.1.1 - Axial and Appendicular Skeleton: The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. This is correlated with a tendency for proximal elements to be involved in supporting the more distal elements of the appendicular skeleton . This consists of two bones, the scapula and clavicle ().
