Compression of a nerve causes loss of afferent and efferent information in it. What is the physiological basis of this?
Seems like it results from a loss of blood flow as the Vasa Nervorum is compressed. Vessels, like arteries or tubules within the kidney, are compressible since they have a vacuous lumen, while an axon is cellular and resists compression. I was thrown off a bit by an answer by a Bryan Krause to this question here, Neurons during Numb feeling, "the feeling of paresthesia is not from loss of blood flow", but, seems like that person was wrong.
