What is the name of the smaller bone on the pinky toe side of your leg below the knee?

The smaller bone located on the pinky toe side of the leg, below the knee, is known as the fibula. The fibula is a long, thin bone that runs parallel to the larger tibia, which is situated more towards the body’s midline. While the tibia bears most of the weight and is involved in bearing loads during walking and running, the fibula primarily serves as a support structure for the ankle and provides stability to the leg. It also plays a role in muscle attachment. Understanding the functional differences between these bones helps clarify why the fibula is identified as the smaller bone on the pinky toe side of the leg.
