Did you know about funny bone?😌


It turns out that your funny bone isn't a bone. It's actually a nerve — one that starts in your spine and travels from your neck, through your elbow and to your fingers (your pinky and ring fingers, to be exact). It's called the ulnar nerve. As one of the three primary nerves in your arm, the main role of your ulnar nerve is to provide sensation in these fingertips, as well as help the muscles in your hand coordinate fine movement and the muscles in your forearm control your grip.
