The superior pubic ramus forms which joint?

The superior pubic ramus forms which joint?

• A. Acetabulofemoral Joint
• B. Sacroiliac Joint
• C. Lumbosacral Joint
• D. Pubic Symphysis

Answer: (D)

The joint formed by the superior pubic ramus is the pubic symphysis. The superior pubic ramus is a part of each pubic bone that meets its counterpart at the midline, where the two pubic bones unite. The pubic symphysis is a secondary cartilaginous joint (amphiarthrosis) with an interpubic disc of fibrocartilage, reinforced by ligaments, allowing only slight movement to absorb stress during walking and childbirth. The other joints listed involve different articulations: the acetabulum with the femoral head forms the hip joint, the sacroiliac joint is between the sacrum and ilium, and the lumbosacral joint is between L5 and S1.
