13 Pelvic (Hip) Girdle Two hip bones (each also called coxal bone or os coxae) Attach the lower limbs to the axial skeleton with strong ligaments Transmit weight of upper body to lower limbs Support pelvic organs Each hip bone consists of three fused bones: ilium, ischium, and pubis Together with the sacrum and the coccyx, these bones form the bony pelvis

14 Base of sacrum Iliac crest Sacroiliac joint Iliac fossa Anterior superior iliac spine Sacral promontory Coxal bone (os coxae or hip bone) Anterior inferior iliac spine llium Sacrum Pubic bone Pelvic brim Coccyx Acetabulum Pubic tubercle Ischium Pubic crest Pubic symphysis Pubic arch

15 Anterior gluteal line Ilium Posterior gluteal line Iliac crest Posterior superior iIiac spine Anterior superior iliac spine Posterior inferior iliac spine Inferior gluteal line Greater sciatic notch Anterior inferior iliac spine Ischial body Acetabulum Ischial spine Lesser sciatic notch Pubic body Pubis Ischium Inferior ramus of pubis Obturator foramen Ischial ramus (a) Lateral view, right hip bone

16 (b) Medial view, right hip bone
Ilium Iliac fossa Iliac crest Posterior superior iliac spine Anterior superior iliac spine Posterior inferior iliac spine Anterior inferior iliac spine Auricular surface Body of the ilium Arcuate line Greater sciatic notch Superior ramus of pubis Ischial spine Lesser sciatic notch Pubic tubercle Obturator foramen Articular surface of pubis (at pubic symphysis) Ischium Inferior ramus of pubis Ischial ramus (b) Medial view, right hip bone Figure 7.30b
