Secured to the axial skeleton by some of the strongest ligaments in the body. Sockets are deep and cuplike and heavily reinforced by ligaments. Formed by a pair of coxal bones (ossa coxae) - hip bones. Each coaxal bone unites with its partner anteriorly and with the sacrum posteriorly. Deep basin structure formed - bony pelvis. Each large coaxal bone consist of 3 separate bones: ilium, ischium, pubis. Fused in adults forming a deep socket - acetabulum -which articulates with the head of the femur.Ilium:Large flaring bone forming the major portion of the coxal bone. Winglike portion is called the ala. Thickened superior margin of the ala - iliac crest.Ischium:Roughly L- or arc shaped. Upper thicker part attaches to the ilium. Lower thinner ramus joins the pubis.Pubis: Pubic bone. Forms the anterior portion of the os coxa. Opening formed by the pubic rami
