Questions: Which tendon contributes to the formation of the oblique popliteal ligament? a) Biceps femoris b) Semimembranosus c) Semitendinosus d) Popliteus

The answer is b) Semimembranosus.

Explanation for each option: a) Biceps femoris - This tendon does not contribute to the formation of the oblique popliteal ligament. It is primarily involved in knee flexion and hip extension. b) Semimembranosus - This tendon contributes to the formation of the oblique popliteal ligament. The oblique popliteal ligament is an expansion of the tendon of the semimembranosus muscle. c) Semitendinosus - This tendon does not contribute to the formation of the oblique popliteal ligament. It is involved in knee flexion and hip extension. d) Popliteus - This tendon does not contribute to the formation of the oblique popliteal ligament. The popliteus muscle is involved in unlocking the knee from a fully extended position.

Summary: The tendon that contributes to the formation of the oblique popliteal ligament is the semimembranosus.
