What is the rough surface at the lateral hipbone called?

• A. ischial tuberosity
• B. iliac crest
• C. iliac tuberosity
• D. greater sciatic notch

Answer: (C)

A tuberosity is a roughened area on a bone where ligaments or muscles attach. On the hip bone, the ilium (the lateral part of the pelvis) has a rough area called the iliac tuberosity, which serves as a site for ligament attachment around the sacroiliac joint. That makes it the best match for “a rough surface at the lateral hipbone.” The other features are not the rough attachment site on the ilium: the ischial tuberosity sits on the ischium (the lower part of the pelvis); the iliac crest is the prominent top border of the ilium; the greater sciatic notch is a gap/notch, not a rough surface.
