‘BONE’ VOYAGE
Exploring the Marvels of the Skeletal System
THE FUNNY BONE IS A NERVE. Have you ever hit your funny bone? Well, you are not hitting a bone at all. This area on the body is part of the ulnar nerve, which goes from your neck to your hand. Bone, muscle, and fat typically protect nerves, but a small portion of this nerve on the back of your elbow is more exposed. So, when you hit your funny bone, named for its location near the humerus bone (a homophone of “humorous”), you’re really bumping into the ulnar nerve.
Make no bones about it; our skeletons are a real rib-tickler of fascinating facts! From the impressive strength of our thigh bones to the tiny marvels of the inner ear, your bones are the unsung heroes of your body. So, rest your bones in a comfy chair because we are about to dig up some of the most shocking skeletal secrets. BABIES HAVE MORE BONES THAN ADULTS. Although babies are tiny, their bodies have many bones in a pudgy, little package. Human babies have about 300 bones compared to an adult’s 206. Many extra bones are entirely or partly made of cartilage, allowing the baby to stay flexible in the womb. Over time, the bones fuse and decrease in number. Fracture rates are highest when kids are around ages 11–15, the critical time for significant growth spurts thanks to growth plates that close as we age. HALF OF OUR BONES ARE IN OUR FEET AND HANDS. Did you know that many of our bones are in the smaller extremities of our body? Nearly half of our 206 adult bones are in our hands and feet! Each foot has 26 bones, and our hands both have 27 bones, which is 106 bones. Our hands even have a bonus bone called the pisiform, located on the outside edge of our wrists.
So, now that you’ve “boned up” on the most fascinating fossil facts, give your skeleton a little nod for the incredible things it does to support you and keep you moving!
