Final answer:
The pelvic girdle attaches to the lower limbs with strong ligaments, including the femur through deep sockets. It is composed of fused bones: ilium, ischium, and pubis, which join at the pubic symphysis. The uterus is held in place within the pelvic cavity by ligaments such as the broad ligament and the uterosacral ligament.
Step-by-step explanation:
The pelvic girdle is essential for bearing the body's weight and for locomotion, securely attaching to the axial skeleton with strong ligaments. The pelvic girdle has deep sockets with robust ligaments to firmly attach the femur to the body and includes two large hip bones, which in adults are formed by the fusion of three pairs of bones: the ilium, ischium, and pubis. The pelvis joins together at the front at the pubic symphysis and with the bones of the sacrum at the back of the body.
Furthermore, several ligaments, such as the broad ligament, round ligament, and the uterosacral ligament, maintain the position of the uterus within the abdominopelvic cavity by attaching it to the pelvic wall and other anatomical structures.
