Which structure is the ligament on the pinky-side lower bone?

• A. Ulnar collateral ligament
• B. Falciform process
• C. Epimysium
• D. Sciatic nerve

Answer: (A)

The main idea is that the ulna is the bone on the pinky side of the forearm, so the ligament located there is the ulnar collateral ligament. This ligament runs along the medial (ulnar) side of the elbow, helping stabilize the joint against sideways (valgus) stress and connecting the humerus to the ulna. The other terms don’t describe a forearm ligament: the falciform process is not a forearm ligament, epimysium is the outer covering of muscle tissue, and the sciatic nerve is a major nerve in the leg.
