For ex: hitting on shin bone hurt more than hurting your knuckles, why? Is it to do with number of nerve endings or the type of bone itself?
In: Biology
It’s a function of the internal biology of the different parts of the body. For example, hitting your “funny bone” is actually you hitting your ulnar nerve, which runs down your forearm. In the spot that people associate with pain, the nerve is relatively unprotected, which is why pain is more intense there
The other typical spot people associate with bone pain, the shinbone, is directly beneath the skin in pretty much everyone. Hits there hurt so much because of the periostal layer. The periost is a layer that covers every bone in your body, and is covered in pain receptors. These receptors send signals directly to the brain, and again, in the shin they’re relatively unprotected by other things to soften the blow
If i remember correctly, it’s because the shin one is very close to the surface. So when you hit against something you are hitting the actual bone. When you hit your knuckles it depends on how you hit them, it could also hurt, but there is more tissue to protect it.
