And for clarification here's a chart:
|Naxi||Hair (on the head only)|
Most of these words can have meaning that extend beyond just the parts of the body. For instance naiyo and maida don't just mean chest and back, but can also mean front and back in much more general terms. For example you can say "naiyo huzono" or "maida huzono" for "the front of the table" or "the back of the table". Also kixa doesn't just mean a human foot. The word can extend to paws and hooves. And we can use these words to mean "something that resembles x", like we do in English. For example: the neck of a bottle, the leg of a chair, a low shoulder on a road, etc.
