What's this called please?

Hi,

Included is the image of a hog nose snake. Despite hours of searching online, I cannot find a clear-cut name for the following:

the two openings in the throat (marked in red)
also that thick double bone in the middle (marked in blue)
and the thin slits above it (marked in green)


thank you!

Almost certain that the area in green is the Jacobsons organ.

After careful consideration and thought, I have concluded that it is a mouth.
