The term FEMUR OR TIBIA is a combination of two bones. The femur is the longest and strongest BONE in the human body, located in the thigh. It connects the hip to the knee joint. The tibia, also known as the shinbone, is the second largest BONE in the body and is located in the lower leg. It connects the knee to the ankle joint. Both the femur and tibia are part of the skeletal system and provide support and stability for the body.
