Which bone is the kneecap?

• A. Ulna
• B. Scaphoid Bone
• C. Patella
• D. Sacrum

Answer: (C)

The kneecap is the patella, a small flat bone that sits in front of the knee joint. It’s a sesamoid bone embedded in the quadriceps tendon, and its main job is to protect the knee and increase the pulling power of the thigh muscles when you straighten the leg. It also helps guide movement as it glides within the groove at the end of the femur. The other bones listed are not at the knee: the ulna is one of the forearm bones, the scaphoid is a carpal bone in the wrist, and the sacrum is a fused section of the spine at the base of the pelvis. These are in different parts of the body, not the kneecap.
