Answer:
the pectoral girdle does not have a solid bony connection to the axial skeleton but rather is supported by a series of muscles derived from the outer layer of hypaxial trunk muscles. The pectoral girdle is designed to absorb the shock of the anuran as it lands on its forelimbs; an elastic, muscular suspension connecting the pectoral girdle to the skull and vertebral column provides this ability.
