And I really don't think it's that different form our own little dominant hand avatar right there that I'm going to use now to click on the term for "hand," go to the page for "hand," where I found the most fun and possibly embarrassing bit of trivia I've found in a long time. It's simply this: The back of the hand is formally called the opisthenar.
To podobne do kursora: rączki, którego użyję, żeby przejść do słowa "ręka". Na tej stronie znalazłem zawstydzającą ciekawostkę. A brzmi ona: Wierzch dłoni nazywa się "opisthenar".
