Quiz 10: The Lower Limb


D Explanation: Femur. The femur is the only bone of the thigh. It is a large, long bone that articulates with the os coxae and two large condyles that articulate inferiorly with the tibia.

E Explanation: Patella. The patella is a sesamoid bone embedded within the tendon of the quadriceps femoris muscle. Its anterior surface is roughened for the attachments to the quadriceps femoris muscle.

B Explanation: Tibia. The tibia is relatively massive because it bears all the weight transmitted from the femur and, in turn, transfers the weight to the ankle. The fibula is not weight bearing. The femur is in the thigh.
