Have you ever found that by just bumping your elbow on something, that you got an odd kind of tingling feeling or an electric shock-like effect?
That instant is often called “hitting the funny bone.” So what is this funny bone, really? Is it an actual bone that makes you laugh? Let’s find out in simple terms.
Is the Funny Bone a Real Bone?
First of all, the funny bone is not considered a real bone. The funny bone is not a bone since its name suggests; it is a nerve. The proper term for this nerve is the ulnar nerve.
This nerve originates in the neck, traverses through the shoulder and down into the arm all the way to the fingers. Near the elbow area, the ulnar nerve passes through a very close quarter between the bone called the humerus. Historically, this led to the moniker of “funny bone” being associated with it.
Where Is the Funny Bone Located?
That funny bone is at the back of the elbow. Touch the inner area of the elbow, and you will feel a little bump. The ulnar nerve runs practically under that little bump area, right under-the-skin area, with not too much muscle or fat blocking it.
So, the impact on that area is a direct hit on the nerve, and an abuzz-and-zap feeling comes about.
Why Is It Called the “Funny” Bone?
The funny bone is named for two main reasons:
- Funny Feeling-An extraordinary sensation tickles or tingles down one’s arm. Several people say it feels funny.
- Word Joke-On the technical side, the nerve involved runs near the humerus bone. “Humerus” sounds rather close to “humorous,” which means funny. Hence, the name is also a double entendre.
What Happens When You Hit It?
When you hit your funny bone, you are actually hitting the ulnar nerve. This causes:
- A sudden shock or tingle
- Numbness in your arm or hand
- A strange feeling in your ring finger and little finger
This feeling usually lasts a few seconds and then goes away.
Can the Funny Bone Get Hurt?
Yes, the ulnar nerve may get injured if it is pressed or bent too much. This may happen if you rest your elbows on hard surfaces for long or just bend your arm too long while sleeping.
In a serious scenario, it can turn into cubital tunnel syndrome, which will cause pain, weakness, or numb fingers.
To prevent further symptoms, you ought to visit your doctor.
In Short: Which Bone is the Funny Bone?
Funny bone is not really a bone. It is the ulnar nerve running around the humerus bone in your elbow. It feels like tingling or buzzing when bumped, hence the word “funny bone.”
