Medical Profession ABV's

Ok so I knew there were ALOT of different titles in the medical field, but I have recently realized theres many many more than I first thought, and the title abv's can be hard to decipher....

I mean for example in nursing you have the following:
CNA or BNA - both the same Certified Nursing Asst. or Basic Nursing Asst.
MA- Medical Asst.
LVN or LPN
RN or ADN or ADRN
BSN
MSN

ect. ect. ect.

I'd love to compile a list of ALL medical profession titles and update the first post accordingly for those of us who need a little help with all these titles and a simple definition. Thanks in advance to all of you willing to help!
