Which of the following pairs includes leg bones?

The correct answer highlights the two primary long bones found in the leg: the femur and the tibia. The femur, also known as the thigh bone, is the longest and strongest bone in the human body, extending from the hip to the knee. The tibia, or shin bone, is located in the lower leg, running parallel to the fibula and providing structural support.

In medical anatomy, recognizing the major bones in the leg is crucial for identifying and assessing injuries, as well as for understanding the overall biomechanics of movement and weight-bearing activities.

Other choices do not reflect pairs of bones that correctly represent leg bones. For instance, the first choice includes the fibula, a bone in the lower leg, but pairs it with tarsals, which are bones of the foot, not the leg. The second option mentions the patella, which is a sesamoid bone that protects the knee joint but is not considered a leg bone in the sense of comprising the skeletal structure of the leg itself. The last choice refers to the coccyx and sacral bones, which are part of the pelvis and spinal column, and therefore do not belong to the leg region.
