Which is a major bone marking of the pelvis?

• A. Coracoid process
• B. Glenoid cavity
• C. Mastoid process
• D. Iliac crest

Answer: (D)

Identifying a major pelvic landmark: the iliac crest. The iliac crest is the upper curved edge of the ilium, forming the top border of the pelvis. It’s the largest and most easily felt bone marking on the pelvic region, making it a key surface landmark for orientation and for muscle attachment areas like the abdominal muscles. The other features come from elsewhere: a coracoid process and a glenoid cavity are on the scapula, and a mastoid process is on the skull’s temporal bone.
