temporomandibular. Rolls nicely off the tongue. And it’s easier to say than “that joint that connects your lower jaw to your upper jaw, right in front of your ear.”
uvuloglossopharyngeal. You’ll notice I really enjoy these long ones; they’re very common in medical texts, of course. I’m all in favor of long words that are truly needed—as opposed to the 50-cent words that are common in what we editors call “Scholarspeak”—that style of writing that could have used half as many words with many fewer syllables to actually say a great deal more.
