Latin and Greek vs English
There is a trend toward using English plurals rather than the traditional Latin or Greek. However, in most cases the latest edition of Merriam-Webster’s Collegiate Dictionary or Dorland's or Stedman's medical dictionary should be followed. Consistency within a manuscript is key.
