6 Things You Didn’t Know about Your Hands
Posted July 28, 2017
We’ve said it before, and we’ll say it again. We’re crazy about hands! Our hands help us accomplish so many tasks, and they deserve a little recognition. They certainly make our lives easier, which is fitting, since this week is Simplify Your Life Week. Keep reading to learn six cool facts you never knew about your hands.
- There are 27 bones in each of your hands. All of those bones are needed to give your hands the flexibility needed to perform everyday tasks, like opening a jar of pickles or turning the key in your car’s ignition.
- The palms of your hands may tan slightly, but the thick layer of dead skin on the palms makes it difficult for UV light to penetrate to the layers underneath. While your shoulders and arms may darken significantly in the summer, your palms won’t, no matter how much sun exposure they get.
- The most common injuries or conditions to the hands and wrists are arthritis, carpal tunnel syndrome, and Dupuytren’s disease.
- There are no muscles in fingers (except for arrector pili muscles that aren’t related to motion—they allow us to have goosebumps). The muscles located in the palm link to the tendons in the finger bones, which allow movement.
- You probably refer to your fingers by the following names: the thumb (although not technically classified as a finger), the pointer finger, the middle finger, the ring finger, and the pinky finger. In the past, various cultures have used different names to describe these digits. For example, the first finger has been called the “toucher,” as well as the “shooting” finger. The middle finger has been called the “longman” and the “long finger.” The ring finger was once named the “leech finger,” the Artzfinger (meaning “doctor’s finger”), and the digitus medicinalis. It was called by these medically rooted names because it was believed that a nerve ran through that finger to the heart, and thus had medicinal powers. The little finger has been called the “ear finger” (as it was used to remove earwax) and the “little man.”
- You might think that the weakest finger is the pinky since it’s the smallest. The ring finger, however, is actually the weakest because it shares a flexor muscle with both the middle and pinky fingers. This is why it is the only finger that cannot be fully extended by itself.
Our hands are truly magnificent, and these facts just barely skim the surface of what they are capable of! Next time you use your hands to catch a ball, write a school essay, or wrap a present, take a moment to appreciate your hands for all they help you accomplish.
