You can just tell list of terminology and don't include "abbreviations".
You're right, there's a clear difference between abbreviation and terminologies, I won like to empathize much on this since OP happen to be a newbie, he can do more research to know better, but for the sake of next time, things like this have already been discussed in the past, he can as well always make use of the forum search button to look on the possibility of a topic being discussed already before creating one.
