Stock Question - Name that part!

OK, one thing that has me puzzled when it comes to rifle stocks is what is the name for the area that forms the front part of the comb.


And as you can see in the picture, there are several styles of this part, even a few others not shown in the picture.
Notice the one on the top left, a vintage Benjamin. The stock comes down the wrist from the action and is almost flat across the comb to the butt. The one below it is an old Sheridan. Notice how that area is swept up to a point at the front of the comb. The two below that are a Kessler and a Crosman. They seem to be sort of a cross between the Ben and Dan. The comb is higher than the Benji, but there's no distict point like the 'Dan.

Is there a name for that area where the comb meets the wrist? And are there different names for the different stiles, like with the comb, there's a straight comb, drop comb or Monte Carlo comb?

I plink, therefore I am.
