Which bone is the hip bone commonly called?

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

Answer: (A)

The hip bone is commonly called the ilium. The hip region is made up of the os coxae, formed by three fused bones: the ilium, the ischium, and the pubis. The ilium is the large, wing-like upper portion that forms the outer, most-visible part of the hip (the iliac crest is the prominent ridge you can feel). Because it’s the largest and most noticeable component, people typically refer to the hip bone as the ilium. The other two parts—ischium behind and below, and pubis at the front—combine with the ilium to form the hip bone, while the sacrum is a separate bone at the back connected to the pelvis.
