Which two bones are the major bones of the pelvis?

• A. Pubis and Ilium
• B. Ilium and Pubis
• C. Ilium and Ischium
• D. Ischium and Sacrum

Answer: (C)

The hips that form the pelvis are each built from three fused parts: the ilium, the ischium, and the pubis. The ilium is the large, upper portion, and the ischium forms the lower, posterior part. Together they make up the main framework of the hip bone, with the pubis contributing the anterior portion. Because the ilium and ischium contribute the bulk of the pelvic bone’s structure, they are considered the major components of the pelvis. The pubis is smaller and sits at the front, while the sacrum and coccyx complete the pelvic ring.
