The tibia, also known as the shinbone, is the larger of the two bones in the lower leg. It's located on the medial (inner) side of the leg. It's a major weight-bearing bone, responsible for transmitting weight from the femur (thigh bone) to the foot. Think of it as the main pillar supporting your body. It connects to the femur at the knee and to the talus (ankle bone) at the ankle.
