The appendicular skeleton consists of the bones of the pectoral (shoulder) girdle, pelvic (hip) girdle, arms, legs, hands, and feet.

The pelvic girdle has massive bones to support the weight of the upper body. Each of the two separate hip bones is a coxa. The coxa each consist of three fused bones: the ilium, ischium, and pubis. The coxa fuse with the sacrum and the coccyx to form the pelvis.
