What's Sooooo Funny?

Why is it called a “funny bone” when it’s not a bone and isn’t funny when you hit it? 

Funny Bone

You know the sensation; you hit your elbow on a hard surface and you feel shooting pains or a “tingling” sensation down the length of your arm to your fingers. What causes that?

The humerous is the upper arm bone that connects your shoulder to your elbow. At the elbow, it joins with the two more bones, the radius and the ulna. The ulnar nerve lies in a ridge along the ulna bone. It controls the movement in your wrist, ring finger and pinky.

Since there is very little muscle around the elbow, the ulnar nerve is close to the surface of the skin. So, when you hit your “funny bone” you are actually hitting the ulnar nerve, which sends a pins and needles sensation from your elbow, down your forearm, and into your wrist and fingers. Which is rarely funny!

Dr. Chris Asks some important questions of interest to San Diego residents - Chiropractor San Diego Dr. Chris Asks...

Why is a "slipped disc" unlikely?
Separating each spinal vertebra is a disc. Its fibrous outer ring holds in a jelly-like material. Because of the way a disc attaches to the spinal bones above and below it, it can't actually "slip." However, a disc can bulge, tear, herniate, thin and collapse. But it can't slip.
Where do most San Diego residents get their first vertebral subluxation?
Being born in a hospital is a common source of vertebral subluxation. Trauma from forceps delivery has been replaced with drugs, vacuum extraction, Cesarean section and births that are "scheduled" to fit the workweek routines of Ob-Gyns. That's why we recommend a chiropractic checkup for every San Diego newborn.
