Final answer:
The femur is proximal to the tarsus, meaning it's closer to the point of attachment to the body than the tarsus which is part of the foot.
Step-by-step explanation:
The femur is proximal to the tarsus. This means that the femur, being part of the thigh, is located closer to the point of attachment to the body than the tarsus, which is part of the posterior foot. The tarsus is made up of seven tarsal bones including the calcaneus, talus, navicular, cuboid, medial cuneiform, intermediate cuneiform, and lateral cuneiform bones, and is located in the foot which is distal to the bones of the leg, such as the femur. Hence, in the context of limb anatomy, 'proximal' refers to a position closer to the torso, while 'distal' refers to a position further away from the torso.
