Here's one you might have already experienced: Fingernails grow nearly 4 times faster than toenails!But did you know that the pink under your fingernails is the blood in your capillaries? You did?Okay how about this: There are no muscles inside the fingers. The muscles which bend the finger joints are located in the palm and up in the mid forearm, and are connected to the finger bones by tendons, which pull on and move the fingers like the strings of a marionette.Here's food for thought: About a quarter of the motor cortex in the human brain (the part of the brain which controls all movement in the body) is devoted to the muscles of the hands.Last but not least, did you know that the wrinkles on the back of the finger knuckles are actually dimples? They mark areas where the skin is attached to the tendon beneath the skin.Now you'll know the back of your hand a little better than you did before!
