Detailed explanation-1: -It is also called pelvic girdle or bony pelvis. This basin-shaped structure of bones associates the legs and the trunk. The pelvic girdle is a part of the appendicular skeleton, which connects the lower limbs to the axial skeleton. The upper limb is connected by the pectoral girdle to the axial skeleton.

Detailed explanation-2: -The hip joint is the junction where the hip joins the leg to the trunk of the body. It is comprised of two bones: the thigh bone or femur and the pelvis which is made up of three bones called ilium, ischium, and pubis. The ball of the hip joint is made by the femoral head while the socket is formed by the acetabulum.

Detailed explanation-3: -The pelvic bones are an attachment for many different muscle groups involving the abdomen, pelvis, perineum, and lower extremities. The muscles limited to the pelvis include the muscles of the pelvic wall and the pelvic diaphragm. The pelvic diaphragm consists of the coccygeus muscles and the levator ani muscles.

Detailed explanation-4: -The pelvic girdle, as I said above, is made up of three fused bones: the ischium, the ilium, and the pubis. The pubis forms the anterior part of the pelvic girdle. It is a flattened, irregular-shaped bone that articulates with the pubic symphysis, a cartilaginous joint.

Detailed explanation-5: -The hip joint is where the pelvic girdle and the leg come together. The hip is joined to the pelvic girdle by many muscles. In the gluteal region, the psoas major and iliacus form the iliopsoas. The large and strong gluteus maximus, gluteus medius, and gluteus minimus extend and abduct the femur.
