Which of the following is NOT a component of the bones of the lower leg?

• A. Tibia
• B. Fibula
• C. Humerus
• D. None of the above

Answer: (C)

The correct choice indicates that the humerus is not a component of the bones of the lower leg. The humerus is actually located in the upper arm and connects the shoulder to the elbow. In contrast, the lower leg specifically consists of two main bones: the tibia and the fibula. The tibia, commonly known as the shin bone, is the larger and stronger of the two, and it bears most of the weight of the body during standing and walking. The fibula is the thinner bone situated alongside the tibia; it provides support and stability to the ankle but does not bear significant weight. Identifying the humerus as part of another limb (the upper limb) highlights the distinction between the bones of the upper and lower extremities, reinforcing an understanding of human skeletal anatomy. The other options, the tibia and fibula, are integral to the structure and function of the lower leg.
