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🤷‍♂️

This isn’t accurate. Motor and sensory nerves share a similar pathway. For example, look at the ulnar nerve (your funny bone). It splits at various points to give rise to partial sensation to your hand and partial to intrinsic musculature of your hand as well as some muscles of your forearm. This is just one example, but most spinal nerves have both sensory and motor function.
