What is the function of the tibia in the skeletal system?

The tibia, commonly known as the shinbone, serves as the primary weight-bearing bone of the lower leg, supporting the body's weight during standing, walking, and running. It also plays a crucial role in stabilizing the knee joint and forming part of the ankle joint by articulating with the fibula and the bones of the foot. Additionally, the tibia provides attachment points for muscles and ligaments, facilitating movement and balance.
