What are the major weight-bearing bones of the leg?

• A. Tibia and femur
• B. Tibia and fibula
• C. Femur and humerus
• D. Fibula and femur

Answer: (A)

The major weight-bearing bones of the leg are the tibia and femur. The tibia, commonly referred to as the shinbone, is the primary weight-bearing bone in the lower leg, supporting most of the body's weight during standing and walking. The femur, or thighbone, is the strongest bone in the body and connects the hip to the knee. It plays a crucial role in weight transfer from the upper body to the lower extremities, especially during activities such as walking, jumping, and running.

Together, the tibia and femur are essential in maintaining stability and facilitating movement, as they bear the forces exerted on the leg during various physical activities. Although the fibula is another bone in the lower leg, it is not a primary weight-bearer as it primarily serves to provide muscle attachment and stabilize the ankle joint. Other options presented do not accurately include the key weight-bearing bones of the leg.
