Why do toddlers wobble?

Some Nerve

What’s the largest unprotected nerve in your body?

Just Like Tiny Drunkards

You’d wobble too if your head were roughly a quarter the weight of the rest of your body. By the time you’re fully grown, your head will weigh only about one-eighth as much as the rest of your body, and therefore be a lot easier to hold up…unless you happen to have an abnormally large head, like Uncle John, who still sometimes wobbles when he walks.

Some Nerve

The ulnar nerve is the medical term for the funny bone, which is neither bone nor funny, although you may find it “humerus” to see your friend writhe in agony after a bump to the elbow.

Why is it so agonizing? It’s a case of poor placement. The ulnar is one of the three main nerves that run from the collarbone to the hand. This particular nerve provides sensation in the pinky and the adjacent half of the ring finger. It also happens to be unprotected, meaning that there’s very little bone or muscle tissue to shield it from trauma. Result: It takes only a slight tap in just the right spot near the elbow to send your entire arm into a tingling frenzy. Interestingly, the temporary discomfort is very similar to the permanent discomfort experienced by sufferers of carpal tunnel syndrome, which affects the ulnar nerve where it passes through the base of the hand.
