The tibia is the larger of the two bones in the lower leg and bears most of the body's weight from the knee to the ankle. It forms the main axis of the leg, articulating with the femur at the knee joint and the talus at the ankle joint. The tibia provides attachment points for numerous muscles and helps maintain stability during standing, walking, and running.
The word "tibia" comes from the Latin word for a flute or pipe, as ancient Romans used to make musical instruments from the shin bones of animals. This name was likely chosen because of the bone's long, cylindrical shape.
