Pelvic Girdle : Hip girdle. Attaches the lower limbs to the axial skeleton. Transmits upper body weight to the lower limbs. Supports the visceral organs. 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
