My best recollection is that sensory nerves are thinner and motor nerves are thicker. The short term paresthesia you get is actually from compression of arteries that give blood to the nerves. When the nerve has a loss of blood, it starts function poorly. The large motor nerves don’t get affected as quickly because there’s generally more blood flow to these and have more stores nutrients. Eventually though, a motor neuron will get affected, look up “Saturday night palsy” which is basically prolonged compression of the radial nerve I believe. Again, this is my recollection from PT school about 6 years ago, so it could be wrong🤷‍♂️

Really? According to most of the websites I have looked at, like https://www.webmd.com/brain/paresthesia-facts, parasthesia is caused by nerve compression, not arterial compression, most mention this as a common misconception. Ig that was the accepted consensus 6 years ago. Thanks for mentioning Saturday night palsy, I didn't know about that. I also wasn't aware of the difference in thickness, that explains a lot. +1.
