Which of the following does not compose the ankle joint?

The ankle joint is primarily composed of three bones: the talus, tibia, and fibula. The talus is a crucial bone that forms the lower part of the ankle, while the tibia and fibula are the two long bones of the lower leg that connect to the talus to form the joint. These connections allow for the movement and flexibility of the ankle, enabling activities such as walking and running.

The femur, however, is the thigh bone and does not directly contribute to the ankle joint structure. It connects to the tibia at the knee joint, but does not participate in the ankle’s movements. Understanding the specific bones that make up the ankle joint is important for grasping how the joint functions and its role in the body's kinesiology. This knowledge is essential for services provided in cosmetology that might involve leg and foot care, as well as for understanding client anatomy during treatments.
