Which bone forms the lateral part of the hip region?

• A. Ischium
• B. Coccyx
• C. Pelvis
• D. Ilium

Answer: (D)

The lateral aspect of the hip region is formed by the ilium. The ilium is the broad, flaring part of the hip bone (os coxae) and includes the large iliac blade and crest that define the outer side of the pelvis. The other bones have different placements: the ischium makes up the lower posterior portion that you sit on, the coccyx is the small tailbone at the base of the spine, and the pelvis refers to the entire ring of bones rather than a single bone. So the ilium best accounts for the lateral hip region.
