The origin of the Gluteus Medius is on which structure?

• A. Ischial tuberosity
• B. Iliac crest of ilium
• C. Pubic symphysis
• D. Greater trochanter

Answer: (B)

The main idea here is where the gluteus medius starts. It originates from the outer surface of the ilium, along the iliac crest, between the anterior and posterior gluteal lines. This broad pelvic attachment provides a sturdy anchor for a muscle whose tendon runs down to insert on the lateral surface of the greater trochanter. That position explains its role as a primary hip abductor and a stabilizer of the pelvis during walking. The other sites aren’t correct: the ischial tuberosity is a sit bone attachment for various hamstrings, the pubic symphysis is a front pelvic joint where some adductor muscles originate, and the greater trochanter is where the gluteus medius inserts rather than originates.
