Innervation for gluteus minimus?

Innervation for gluteus minimus?

• A. femoral nerve
• B. superior gluteal nerve
• C. inferior gluteal nerve
• D. nerve to piriformis

Answer: (B)

Innervation for gluteus minimus comes from the superior gluteal nerve. This nerve, arising from the sacral plexus, exits the pelvis above the piriformis and then supplies the gluteus medius and minimus (as well as tensor fasciae latae). The inferior gluteal nerve goes to gluteus maximus, the femoral nerve supplies anterior thigh muscles, and the nerve to piriformis innervates the piriformis. So the superior gluteal nerve is the source for gluteus minimus.
