Verified step by step guidance
1
Step 1: Begin by identifying the three bones that compose the ankle joint. The ankle joint, also known as the talocrural joint, is formed by the articulation of the tibia, fibula, and talus.
Step 2: Understand the anatomical location and function of each bone. The tibia and fibula are the two bones of the lower leg, while the talus is a tarsal bone that connects the leg to the foot.
Step 3: Compare the listed options to the bones that form the ankle joint. The options provided are: Femur, Talus, Tibia, and Fibula.
Step 4: Recall the location of the femur. The femur is the thigh bone and is not part of the lower leg or the ankle joint. It articulates with the pelvis at the hip joint and the tibia at the knee joint.
Step 5: Conclude that the femur is NOT one of the three bones that compose the ankle joint, as it is anatomically separate from the structures forming the ankle.
