I don't know about radial bones, but if you want body hair on your Poser people, that's when you need a skin texture.

What do you think those blue lines are on the Poser people's arms and legs? Veins are visible even when the figure's skin is white (Chalk in the Apple Color Picker). I've even seen "veins" on the sleeves of Posette's dress shirt, although they don't belong there.
