Limb Girdle Comparison

The limb girdles form the foundation for the movement fo the limbs. The pectoral girdle is connected to the forelimbs (e.g. our scapula and clavicle). The pelvic girdle attaches to the hindlimbs (e.g. our pelvis). Together with our limbs the girdles form the appendicular skeleton. As you compare the limb girdles of the animals note the differences in size and attachment. Understand how these differences reflect the uses the girdles must serve in fishes, birds and mammals.
