Final answer:
The pelvic girdle consists of four bones: two hip bones, the sacrum, and the coccyx. Each hip bone is formed by the fusing of three bones: the ilium, ischium, and pubis.
Step-by-step explanation:
The pelvic girdle is a bony structure that attaches the lower limbs to the axial skeleton and is integral for supporting body weight and for locomotion. It consists of four bones: two hip bones (each termed a coxal bone), the sacrum, and the coccyx. Each hip bone is comprised of three fused bones - the ilium, ischium, and pubis. The right and left hip bones join anteriorly at the pubic symphysis and posteriorly to the sacrum, which together with the coccyx, form the complete pelvis.
