Which muscle is a slender hip adductor and knee flexor?

• A. Gracilis
• B. Piriformis
• C. Tibialis Anterior
• D. Soleus

Answer: (A)

The muscle that fits being slender and performing both hip adduction and knee flexion is the gracilis. It’s a long, strap-like muscle along the inner thigh that crosses the hip and knee joints. At the hip, it pulls the thigh inward (adduction), and at the knee, it helps bend the leg (knee flexion). Its anatomical path—from the pubic ramus to the medial surface of the tibia (as part of the pes anserinus)—explains why it can affect both joints. The other muscles listed are not involved in both actions: the piriformis is a deep hip external rotator, the tibialis anterior dorsiflexes the ankle, and the soleus plantarflexes the ankle, none of which combine hip adduction with knee flexion.
