Tibia:The larger bone in the lower leg that bears most of the body's weight and articulates with both the knee and ankle joints.
Ankle joint: A complex joint where the tibia, fibula, and talus meet, allowing for foot movements such as plantarflexion and dorsiflexion.
Ligaments:Fibrous connective tissues that connect bones to other bones, providing stability to joints; several ligaments around the ankle connect to or are supported by the fibula
