Is the foot part of the leg?

But, the question isn't "is the foot alone sufficient to indicate the entire leg?" The question is, essentially, do "the thigh, knee, calf, and foot" (together) all belong to "the leg," or do they belong to two separate groups, "the leg," and "the foot."

This is clearly inclusive of the entire leg, the only part being in question is how far the inclusiveness continues to be in effect; so therefore I fail to see the relevance of your "if only [single body part] is involved" argument.
