Going out on a limb here (pun intended)...I'm writing a paper in which I need to refer to various sections of the human leg from upper thigh to knee to calf and ankle. However, "calf" covers a fairly large area. Without having to go into specific leg muscle identification (semitendinosus, biceps femoris, etc.) which could be confusing as they overlap and can be found with Google.
Is there a (standard) anatomical way to describe (cylindrical) sections of the leg from top to bottom?
