Anatomy of numbers or Names for parts of numbers?

[navalon]

There are diagrams on the web giving technical names for the parts of letter forms, such as "counter," "ascender," "bulbous terminal," etc.  Are there any similar diagrams for the parts of numbers?  

I'm specifically interested in 19th century type, but I assume the same names would apply.

Thanks!

I am not aware of any anatomy terms that would apply just to figures. You just have the regular stems, arcs, counters, horizontal strokes …

Ralf is right; there aren't any names specific to numbers.

I couldn't find any myself.  So, can anyone suggest what terms would be appropriate for the following number parts?  Thanks!

[Riccardo Sartori]

A: (some depending on the style) stem, leg, diagonal stroke.

B: left arc(h).

C: vertical stem/stroke.

D: bowl.

E: crossbar.

F: spine.
