What’s Ulnar Nerve?

A major nerve that moves from the arm to the hand

I was an assistant professor at a university, then I quit the job for personal reasons. If I had persisted there, I would have been an associate professor by now.
I don’t have a designation now, but nobody can take away the knowledge from me. Plus, I had all the time to myself, so I learned all sorts of things and made my knowledge more profound.
Now, whenever I talk, knowledge just erupts like a volcano.

For example, today my daughter was sitting on a chair, and the naughty son pushed her. She was hurt at her elbow. I disciplined both of them.

I advised the daughter to be more vigilant of threats.
I warned the son to not behave like a brat and to not hurt others.

Then, I moved to science.
I explained:
The ulnar nerve passes through our elbow.
When our hand is straight, it is covered, but when we bend the elbow at an angle, the nerve gets more exposed — and if we hit it, it can get traumatized.

I asked my daughter what kind of trauma that would be. She answered, “Mechanical.” That’s correct. Any force or pressure is mechanical.
