Labeling a diagram requires applying knowledge of a concept. It is an effective form of self-assessment, enabling students to check their understanding. In the following Tibia and Fibula labeled diagram, we have shown several important parts of the human body muscles. We have an Articular surface of the medial condyle, medial condyle, tibial tuberosity, Head of the Fibula, lateral malleolus, articular surface, distal tibiofibular joint, Fibula, and more. It should be noted here that labeling a diagram serves as useful feedback to a teacher, too, as it provides information about what students understand and what they still need to learn.
