The tibia and fibula are the two long bones in the lower leg. They connect the knee and ankle, but they are separate bones. The tibia is the shinbone, the larger of the two bones in the lower leg.
Answer:The tibia is the main bone of the lower leg, forming what is more commonly known as the shin. It expands at its proximal and distal ends; articulating at the knee and ankle joints respectively. The tibia is the second largest bone in the body and it is a key weight-bearing structure.
