When the ulnar nerve is struck at the medial edge of the distal humerus, it's not humorous, but who knows? the connection between these two homonyms may have led to the designation 'funny bone'. I present below a list of definitions for similar pairs (sometimes, triples) of homonyms. As the title implies, at least one word in each homonym set comes from a scientific vocabulary (but all words appear in Webster's Third edition). As an additional aid, the number of letters in each word is indicated.
