Phalanx also means finger to most students of history. It is, after all, Greek for Finger (secondary to Aristotle dubbing the bones so).
What's your point? It seems to be that medical terminology (or the expert body of knowledge that distinguishes someone with anatomical or medical knowledge from the layperson) is an artificial construct which imposes undue restrictions on the easy transfer of this knowledge - guild behaviour.
Every realm of knowledge has its own language which must be learned in order to be proficient. In briefly reading your other replies in this thread, it seems like you feel that computing and programming don't have these restrictions - that is absolutely not true, just ask anyone who has been trying to learn programming themselves but is stuck on the difference between a method and a function (only to find out they are the same thing).
It is not possible to be an expert without gathering the knowledge, the language, and the real understanding necessary to partake in the field. Anything else is simple arrogance, to assume that any specialised field that people spend decades learning, is actually just arcane crud and cruft that disguises the simplicity hidden within
