An interesting point is you will see a bone in the carpel series called the Trapezium
As you will all be aware there is a muscle in the shoulder/neck also called Trapezium (see The Guvnor or Jester for details)
This is similar to how there is a valve in the heart called the Bicuspid, which is also the name for a tooth (the one between the "fang" and the molar, the one that has 2 peaks to it (the molars have 4)) - so depending on whether you are talking to dentist or a cardiologist when you say "Bicuspid", they will take it to mean something different
In Kung Fu, there is a strike which knocks out the bicuspid tooth, and a strike which (is supposed to) knock out the bicuspid valve in the heart (Dim Mak)
Just at we say "Rolling" - in Ju Jutsu this means grappling sparring, in Ninpo it means ukemi kaiten, and in Wing Chun it means Chi Sao sparring
