Thanks for this. I had similar questions. I am also still wrapping my head around bone types and think I need to go back and rewatch the presentation of these parts so I can now understand them in the context of a model. In my mind to this point I had thought of MCH bones as the skeleton inside a body and DEF bones as children of the MCH bones which act as muscles that deform the body based on the movement of the MCH bones but it seems I’ve got this all wrong and I’m still not sure why the Clamps aren’t MCHs. I take the point (and greater experience of Wayne) that we don’t need the CTL prefix once you’re experienced but as a beginner I’m finding it really confusing to try to remember what each bone is doing is when some names allude to function and others don’t.
