Quizplus · Accepted Answer

The humerus bone in the upper arm has a trochlea, which is a spool-like structure that articulates with the ulna bone in the forearm. It also has a capitulum, a round structure that articulates with the radius bone in the forearm. Additionally, the humerus has a greater tubercle, which is a prominent bump on the lateral aspect of the bone where the muscles that move the arm attach. The tibia bone in the leg has a medial malleolus, the femur bone in the thigh has a greater trochanter, and the fibula bone in the leg has a lateral malleolus, but not the distinct features described in the question.
