Background information 
The Denobulan language features in a deleted scene from , in which Phlox advises Hoshi Sato that, although she meanwhile has some minor wounds, they should continue their Denobulan lessons. In the final draft script of "Minefield", it was repeatedly indicated that concentrating on Sato's learning of Denobulan was one way Phlox tacitly tried to motivate Sato into thinking about other things than her injuries. Denobulan vocabulary established during the scene includes the following:

Y'sah mai-kaam.
The thyroid gland.

Y'sah dee-katta.
The hypothalamus.

Y'sah duhfku.
This could be mistaken for the "big toe".

Y'sah kut'du'thaal.
The xiphoid process.

There was also a Denobulan word (though not used on screen) for the pericardium. Phlox estimated that this was "simpler" to remember than the Denobulan statement meaning the xiphoid process. ( deleted scene)
