Question: what are the similarities between the pectoral and pelvic girdles?
Answer: Pelvic and Pectoral Girdles: The pelvic and pectoral girdles serve as points of attachment for the appendicular skeleton to the axial skeleton. The pectoral girdle (also called the shoulder girdle) attaches the upper limbs (arms). This girdle consists of two bones: the scapula and the clavicle.
